What is Hysteroscopy in Fertility Treatment? When infertility is observed in a couple, doctors begin to use expensive methods for diagnosis, which leads to IVF treatments later. Hysteroscopy is one such method. It enables doctors to visualize the inside of the uterus directly and should carry out differential diagnosis of several problems like fibroids, adhesions, or polyps that can prevent proper or good embryo implantation. From hysteroscopy at Dr. Aravind’s IVF, many couples have gained usefully for their fertility just because their uterus is in the best condition for pregnancy. Why Hysteroscopy Is Necessary Before Performing IVF Before going to choose the best IVF center, couples want to make sure they've covered all angles that could affect the success of their endeavor.

Vacant properties are increasingly susceptible to weather damage, especially during colder months. Property owners, investors, and servicers often overlook critical maintenance procedures until it’s too late. One of the most crucial services that help preserve the integrity of vacant or foreclosed homes during freezing conditions is winterization. Companies like Safeguard Properties specialize in protecting these assets by offering comprehensive seasonal maintenance, ensuring they are secured and preserved against potential risks. When a property is left unoccupied, particularly in cold climates, its plumbing and heating systems become vulnerable. Pipes can freeze and burst, heating systems can fail, and moisture intrusion can lead to mold growth or structural deterioration. Winterization …  ( 8 min )

While some companies move 100% of their infrastructure to the cloud some prefer a hybrid system which combines on-premises infrastructure with cloud services. This is a connection from an on-premises server to AWS through the internet. First you create a virtual private network in your VPC, as a result you are provided with a VPN endpoint which lives in the virtual private gateway. This VPN endpoint is then provided to your on-premises device (router) that support IPsec (Internet Protocol Security), Your router and VPN endpoint then uses IPsec to authenticate each-other. Once the encryption is established a secure tunnel is created over the internet which will facilitate the connection between your on-premises network and VPC. After this is done, your on-premises network can now see AWS subnets, and AWS can see your on-premises subnets. The connection does not have to go through the public Internet instead it goes through a private fibre link. This private fibre link is gotten by contacting a telecom provider who then provides a dedicated link from your on-premises network to AWS direct connect location. From these locations your connection then enters a logical lane through a virtual interface which is tied your VPC through a virtual private gateway or transit gateway (this can enable connection to more than one VPC) Now your servers can interact and they do not need to go through the internet, they just utilize these fibre cable connections. Site-Site VPN connections are fast to set up, cheap, and they are perfect for small or medium traffic, But they depend on the public internet which may not always be reliable and increase latency. Direct Connect connections are reliable and cheaper since AWS gives discounts if you move a lot of data, But are more expensive upfront and takes lots of time to set up. Conclusion Chooses between the two connection models really boils down to your use case, availability, the size of your organization, safety and compliance laws and finances.  ( 7 min )

So, you are building an application and need a login form. In it, you’ll get the user's email and password, send them to an API, and... something happens. The user is logged in afterwards. But what is that something? How does your application decide who gets in and what they get to see? This is the first article in a series called "Let's Sketch Identity." These blog posts will use my notes from when I started learning about identity concepts as a Developer Advocate.

The trillion-dollar question haunting Silicon Valley isn't whether artificial intelligence will transform the world—it's what happens when the golden age of just making AI models bigger and more powerful comes to an end. After years of breathless progress driven by throwing more data and compute at increasingly massive neural networks, the industry's three titans—OpenAI, Google, and Anthropic—are discovering that the path to truly transformative AI isn't as straightforward as the scaling laws once promised. The bottleneck has shifted from raw computational power to something far more complex: making these systems actually work reliably in the real world. For nearly a decade, the artificial intelligence industry operated on a beautifully simple principle: bigger was better. More parameters,…  ( 27 min )

Introduction JSON is everywhere - from web services to IoT. But here’s the catch: most popular JSON libraries were written with desktops and servers in mind, where nobody cares about a few extra megabytes. On microcontrollers, especially Cortex-M devices, every byte and every millisecond counts. Sure, you can push raw C structs around and even write them directly to a config file. It works, but debugging turns into a painful quest. At some point I got tired of wrestling with JSON on STM32: writing endless boilerplate to walk through cJSON trees, hunting memory leaks, and guessing where malloc would betray me next. That’s when JsonX was born - a lightweight, minimalistic wrapper around cJSON, designed specifically for MCUs and RTOS. What JsonX Brings to the Table Automatic mapping JSON C…  ( 7 min )

Let’s face it—most of us sit way too much. Office work, commuting, sitting at home… it all adds up. And after a while, your back and neck start complaining. That’s why a lot of people are trying a standing desk for office use. We weren’t built to sit in a chair for hours. Think about it—hunching over, shoulders rounding, neck craned toward the screen. By the end of the day, your back and shoulders are yelling at you. A standing desk changes things without you thinking about it. Your monitor is at eye level, your elbows around 90 degrees, and your spine stays more aligned. You don’t have to keep reminding yourself to “sit straight.” Here’s the funny part: standing helps you pay attention. You move a little, shift your weight, maybe stretch—your blood keeps flowing, and your energy stays steadier. Here’s the thing—you don’t have to stand all day. That can get tiring too. The real benefit comes from switching. Stand for emails, sit for deep focus, then back up on your feet when you feel sluggish. Not all standing desks are created equal. If it wobbles or is hard to adjust, you won’t use it. That’s why the Navodesk® Pro Standing Desk is a game-changer. Smooth height changes, solid stability, and a clean look. It’s the kind of desk that actually makes switching between sitting and standing easy. That’s the whole point—working in a way that supports your body instead of wearing you down. Tired of aching backs and afternoon slumps? A standing desk can help. You don’t need to stand all day. Even a few hours of alternating can improve posture, boost focus, and make work feel less draining. Once you get into the rhythm, it feels natural. And honestly? You’ll probably wonder why you didn’t try it sooner.  ( 7 min )

These days, I feel like I’m walking alone. I’m in my final year of B.Tech, and everywhere I look, people seem to have figured out their paths. Placements, projects, internships, communities — everyone is moving, running, achieving. And then there’s me. Sitting with my laptop, staring at lines of code that blur into nothing. It’s not like I’ve done nothing. In fact, I’ve been doing tech things since my very first year — projects, coding competitions, internships, open-source, hackathons. From 1st year till now, I’ve kept showing up. I’ve worked, learned, built, tried. And still, somehow, I feel invisible. Like no matter how much I do, it’s never enough for anyone to notice. It’s not just the errors on the screen that wear me down — it’s the silence around me. No teammates pinging me to collaborate. No friend saying, “Let’s build this together.” No late-night debugging calls. Just me, my screen, and a room that feels too quiet. Sometimes I wonder if I’m invisible. Like if I stopped showing up, no one would notice. Not in class, not online, not even in the dev community I admire so much. It hurts to scroll past other people’s wins — their open-source contributions, their internship offers, their shiny projects — while I sit here, questioning my worth. I go to sleep with thoughts like, “Maybe I’m not cut out for this. Maybe I don’t belong in tech. Maybe people just don’t like me.” And honestly? Some nights, I believe it.  ( 6 min )

Introduction Modern applications juggle tasks like reading databases, calling APIs, or processing files. If handled poorly, these time-consuming operations can freeze an application's main thread, leading to a sluggish and unresponsive user experience. Asynchronous programming is the solution. In .NET, the async and await keywords provide a powerful abstraction, allowing you to write non-blocking code that reads as cleanly as synchronous code. But async/await isn't magic—it's syntactic sugar that transforms your methods into a sophisticated state machine. In this article, we'll explore why async/await is essential, see it in action, and then pull back the curtain to reveal the underlying mechanisms the compiler uses to make it all work. async/await is a Game-Changer 🚀 Imagine your app…  ( 10 min )

One of my hobbies is to "re-invent" already done things, such as building a CPU simulator, create my own ISA and what-not. While happily coding away on an instruction decoder with some simulated EEPROM chips, it hit me: why don't I use signals to simulate wiring between the components? I used them in Flutter and I need the same kind of reactivity here too. Guess what? Signals were originally intended for that. WHO KNEW?! :D trivia: signals got their name after digital circuit modeling research in the 1970s1. In a super-simple form, a D-FlipFlop samples an input pin when another signal (clock transitions from lo to hi2. When transition happens, the state of the input pin (hi or lo) is latched in and is output to q. The inverse of that latched in value is output to q̅ (q-bar). A couple of hours of playing around and I ended up with the following piece of code to simulate a D-FlipFlop: class DFlipFlop { final clock = Input(false); // Input is a signal final input = Input(false); late bool _prevQ = input.value; late final q = computed(() { final clk = clock.value; if (clk) { // detect rising edge, sample input pin _prevQ = input.value; } return _prevQ; }); late final qBar = computed(() => !q.value); } That's it! Essentially it boils down to the following core concepts: input pins are signals output pins are derived values (computed) connections/wires between input and output pins are effects For the full code sample, check out this gist: 1. https://youtu.be/Jp7QBjY5K34?t=171 2. lo and hi values are often "mistyped" to indicate logical high and low voltage levels  ( 8 min )

Python Lambda Functions: The Art of Writing Powerful Code in a Single Line Have you ever been writing a Python script and found yourself creating a small, throwaway function just to perform one simple operation? Maybe it was to double a number, check if a string contains a keyword, or sort a list of tuples. If so, you’ve encountered the perfect use case for one of Python’s most elegant, yet sometimes misunderstood, features: the lambda function. Often called anonymous functions, lambdas can seem cryptic at first glance. But once you understand their purpose, they become an indispensable tool for writing cleaner, more concise, and more "Pythonic" code. This guide will demystify lambda functions completely. We'll cover what they are, how they work, when to use them (and when not to), and e…  ( 11 min )

Switching from asdf to mise wasn’t just a fleeting developer whim - it’s the result of years of wrangling with version managers, misplaced shims, and dubious bash scripts. Mise, written in Rust, simply runs faster, feels smoother, and doesn’t make my shell configuration look like a post-apocalyptic cargo cult. asdf had been the trusty sidekick for managing tool versions: Node, Python, Terraform, even that one [VHDL](url) project that only seemed to make sense very late at night years ago. It's polyglot, versatile, and compatible with nearly everything... except, apparently, my desire to not wait several seconds for basic operations.

Introduction Ever wish you could peek into the future and make decisions that hold up no matter what happens? Scenario planning is the practical alternative to a crystal ball. Rather than betting your strategy on a single forecast, it helps teams imagine several plausible futures, surface the biggest uncertainties, and build plans that work across multiple outcomes. The point: prepare, don’t predict. What scenario planning is A disciplined way to think about uncertainty by creating a handful of vivid, plausible futures and testing how your business would fare in each. Focus = preparation and resilience, not perfect prediction. Everyday analogy: instead of planning for only a sunny event, prepare tents, an indoor backup, and traffic reroute options. Why a single forecast is risky Traditio…  ( 7 min )

How this dynamic duo turns chaos of metrics into a clear window into your software's soul. In the complex, distributed world of modern software, things break in unexpected ways. A microservice might slow down, a server's memory might silently fill up, or an API might start throwing errors. Relying on users to report these issues is a recipe for frustration. The only way to truly understand what's happening inside your systems is to listen to what they're constantly telling you: a story told through metrics. But raw metrics are a firehose of data. To make sense of it, you need two things: a powerful, scalable system to collect and store this data, and a beautiful, flexible way to visualize it. This is the legendary pairing of Prometheus and Grafana. Prometheus is an open-source systems moni…  ( 9 min )

Combining Docling capacities with IBM Cloud Code Engine serverless compute capacities Serverless computing has revolutionized how developers build and deploy applications by abstracting away the underlying infrastructure management.

Since its first release the CouchDB ecosystem has become quite substantial — think adding everything from hammocks to a chaise. It’s not a marketing-driven technology, so if you needed more evidence of how widely CouchDB is used, you’re about to find a wealth of repos that have received contributions in the last weeks and months. Given CouchDB’s focus on long-term reliability, you’ll also find some older packages still humming along. In part one of this series we kicked off with some history to understand CouchDB’s origins. We looked at the problems it addresses, and how those problems have evolved (or persisted, put another way) since. In part two we looked more closely at CouchDB’s core features and some exemplary use cases. This third and final part aims to provide a community introduc…  ( 11 min )

Learn JavaScript hoisting in simple terms. This beginner’s guide explains how var, let, and const behave, with clear examples of variable and function hoisting. When you start learning JavaScript, you may notice that variables and functions sometimes behave in unexpected ways. This is because of a feature called hoisting. Hoisting is one of those topics that confuses beginners, but once you understand it, your code will make much more sense. In simple terms, hoisting is JavaScript’s default behavior of moving variable and function declarations to the top of their scope before code execution. By the end of this guide, you’ll understand: What hoisting means in JavaScript. How hoisting works with variables. The difference between var, let ', andconst` in relation to hoisting.

Boilerplates have long been the go-to for developers starting new projects. They provide a ready-made structure, enforce standards, and save us from writing the same setup code again and again. But with AI-powered tools like GitHub Copilot, ChatGPT, and other code generators, the question arises: do we still need boilerplates in 2025? AI can scaffold a project in minutes, generate configs, and even suggest best practices on the fly. It feels like the gap boilerplates once filled is now being covered by smarter, context-aware assistants. On the other hand, boilerplates still offer: Consistency: Everyone in the team starts with the same foundation. Standards baked in: Security, logging, CI/CD, and architecture patterns aren’t left to chance. Battle-tested reliability: AI may hallucinate, but boilerplates capture lessons from real-world deployments. So maybe it’s not “AI vs boilerplates” but rather AI + boilerplates—where AI personalizes and extends the foundations boilerplates provide. What do you think? Will boilerplates fade away as AI gets better? Or do they still have an irreplaceable role in ensuring standardization and reliability? I’d love to hear how you and your team approach this—especially if you’ve tried blending AI with boilerplate setups.  ( 6 min )

Introduction Project success is never guaranteed, but a Risk Assessment Plan increases the odds of achieving objectives. It provides a structured way to anticipate risks and manage them effectively. Risk assessment is about foresight. It examines possible scenarios that could hinder project performance and develops strategies to mitigate them before they cause setbacks. The plan includes a risk register, analysis methods, impact assessment, and contingency strategies. These elements work together to minimize surprises during execution. A clear Risk Assessment Plan ensures that team members know what risks exist, who owns them, and how to respond. This readiness improves efficiency and decision-making under pressure. Beyond individual projects, risk assessment builds a culture of awareness within the organization. Teams learn to anticipate problems and respond with agility. By implementing a Risk Assessment Plan, project managers reduce uncertainty and increase control over outcomes, setting the foundation for consistent project success.  ( 6 min )

Recently, I was assigned a task that opened my eyes to the power of Redux. The task was simple in theory: have one central point for switching between branches in an admin dashboard. The dashboard had multiple components, Orders, Products, Stock Valuation, and whenever a user selected a branch, all these components needed to show only the data for that branch. At first, my instinct was to put the branch in the URL as a query parameter, like: /dashboard?branch=NairobiWarehouse This would work for a single filter, but my senior quickly pointed out the downsides. Imagine later adding filters for date, status, or user. The URL would become long and messy. This is exactly where Redux shines. Redux is a state management library for React apps. Think of Redux like a note on your fridge:…  ( 7 min )

As a React developer, I’ve always been conscious of how I manage state, especially when integrating with external data sources or global stores. Over the years, I’ve used different patterns—useEffect hooks, custom subscriptions, and third-party libraries like Redux or Zustand. But recently, while working on a React 18+ project, I discovered useSyncExternalStore, and it genuinely changed my perspective on syncing external state with React components. In one project, I needed to build a real-time dashboard listening to data from a custom in-memory store. Initially, I wrote the subscription logic using useEffect and useState. However, I ran into tricky bugs—sometimes the UI wouldn’t reflect the latest state correctly during fast updates, and in SSR scenarios, the server-rendered content didn’…  ( 7 min )

I once carried out a skills gap analysis on myself as a DevOps engineer, looking for my next challenging opportunity. I realised that although I had built smaller projects, I hadn’t yet executed a production-grade, full-blown cloud-native project that combined all the essential DevOps practices.

Introduction Business dashboards are valuable only when they combine speed, accuracy, and usability. In modern analytics, every second counts—especially when working with large datasets. Tableau is one of the most popular tools for data visualization, but as the volume of data grows, efficiency becomes critical. One area where many users encounter performance issues is when creating groups in Tableau. While Tableau provides a built-in "Create Group" feature, it can become slow with large datasets because it loads the full domain of a dimension. This often leads to frustrating delays in dashboards, particularly when working with millions of rows.

No matter how experienced you are, bugs are inevitable. They sneak into code during late-night coding sessions, sudden requirement changes, or even the simplest refactor. This guide walks you through the mindset, techniques, and tools every developer should know to track down and fix issues with confidence. 1. Testing vs. Debugging: Know the Difference Before diving in, it’s important to separate testing from debugging: Testing is about detecting problems. It tells you something is wrong by running automated tests, QA checks, or manual verifications. Debugging is about diagnosing and fixing those problems. It’s the detective work that starts once a test fails or a user reports a bug. Think of testing as the alarm and debugging as the investigation. 2. Breakpoints: Your First Line of Defens…  ( 8 min )

Introduction If you’ve ever worked on a product with multiple engineers across frontend and backend, you’ll know how quickly things can fall apart without shared rules for handling data. Small differences—like whether dates should be UTC or local, or if null and [] mean the same thing—can create bugs that are painful to debug but trivial to avoid. I’ve been in that situation many times, and over the years I’ve settled on a set of lightweight standards that keep things predictable. This post is about those standards: pragmatic, easy-to-adopt rules that have saved me (and my teams) countless hours. Consistency: Everyone interprets data the same way.

Then, we’ll see how to refactor it for better maintainability, extensibility, and testability. *The Example Code public class EpsilonGreedyRecommender { private int nItems; private double epsilon; private int[] counts; private double[] values; private Random random; public EpsilonGreedyRecommender(int nItems, double epsilon) { this.nItems = nItems; this.epsilon = epsilon; this.counts = new int[nItems]; this.values = new double[nItems]; this.random = new Random(); } public int recommend() { if (random.nextDouble() < epsilon) { return random.nextInt(nItems)…  ( 8 min )

Every developer I know is obsessed with the wrong metrics. They argue about whether Claude beats GPT-4, whether Gemini's reasoning is better than ChatGPT's, whether the latest model from Anthropic or OpenAI will change everything. They're fighting yesterday's war. While we debate which model generates better code or writes more coherent essays, the real transformation is happening in a completely different layer of the stack. The companies that will dominate the next five years won't be the ones with the smartest individual models. They'll be the ones who solve AI orchestration at scale. The model wars are ending. The infrastructure wars are just beginning. We're living through the tail end of the "bigger model, better results" era. For the past three years, every breakthrough felt like it…  ( 10 min )

Everyone's talking about MiMo-Audio, but the real opportunity is how merging voice and language will unlock faster products and open new markets. 7B parameters and 100M+ hours of sound is impressive. But the shift is bigger than model size. Audio and text are finally one canvas. When voice and language live together, complex workflows get simple. You remove awkward handoffs between transcription, translation, and analysis. Teams ship one model, one objective, and far less glue code. That means lower cost, faster iteration, and better user experiences. It also means accessibility gains for global and neurodiverse users. In a recent pilot, a support team unified calls and text notes. Real‑time translation, emotion transfer, and summaries cut handle time by 22%. Escalations dropped 18% in 30 days, and CSAT rose from 4.1 to 4.5. One workflow change produced a measurable business win. ↓ A simple 30‑day plan to test this. • Pick one journey where voice friction hurts outcomes. ↳ Onboarding, support QA, or post‑meeting notes are low‑risk starters. • Define two metrics to move, and a hard guardrail. ↳ Time saved, error rate, and consent compliance are good anchors. • Ship to 10% of traffic, review weekly, then expand. ⚡ You will reduce ops drag and unlock new product experiences. ⚡ Your roadmap shifts from patching to truly multimodal value. The next interface is your voice. What's stopping you from shipping a voice+text feature this quarter?  ( 6 min )

Bychristine September 23, 2025 And Why We Should Care Based on some solid reporting by Joel Drapper and Ellen’s breaking details So, the Ruby community just went through something wild, and I think we need to talk about it. On September 9th, Ruby Central basically took over the RubyGems GitHub repos and gem ownership without asking the people who’ve been maintaining them for years. It’s… not great. The Story (As Best I Can Tell) Joel Drapper did some really impressive investigative work here, and here’s what seems to have happened: The Money Problem: Ruby Central lost $250k a year from Sidekiq after they had DHH speak at RailsConf 2025. That left them pretty much dependent on Shopify for funding. The Pressure: Shopify apparently said “take control of RubyGems or we’re pulling our f…  ( 7 min )

Depois de aprender sobre loops, chegou a hora de organizar melhor o código com funções. Funções permitem reaproveitar código, deixar o programa mais limpo e fácil de entender. ⚙️ 1️⃣ O que é uma função? Uma função é como uma caixinha de código que executa uma tarefa específica sempre que você chama ela. 📝 2️⃣ Criando uma função def saudacao(): print("Olá, seja bem-vindo ao meu programa!") def → palavra-chave para definir a função. 🔔 Para usar a função: saudacao() 🧩 3️⃣ Funções com parâmetros Podemos deixar funções mais flexíveis passando informações: def saudacao_nome(nome): print(f"Olá, {nome}!") saudacao_nome("Victor") 🎯 4️⃣ Funções que retornam valores Às vezes queremos que a função calcule algo e devolva o resultado: def soma(a, b): return a + b resultado = soma(5, 3) print(f"O resultado é {resultado}") ⚡ 5️⃣ Escopo de variáveis Variáveis criadas dentro da função só existem nela. Variáveis criadas fora da função podem ser acessadas dentro (mas com cuidado). x = 10 def mostrar(): print(x) # usa a variável global mostrar() 📝 6️⃣ Exercícios Práticos 💡 Tente resolver antes de olhar a resposta. 1️⃣ Crie uma função que receba um número e diga se ele é par ou ímpar. “Menor de idade” se = 60  ( 6 min )

Abstract The concept of a derived identity represents both a conceptual and practical model in which an individual’s physical and personal attributes—including biometrics, documentary data, and personalization signals obtained from devices such as printers—are transferred into the digital realm through robust authentication processes. This convergence allows the creation of a unique digital fingerprint, comparable to DNA in the physical world, ensuring traceability, fraud resistance, and end-to-end cryptographic control. This article proposes a reference architecture for building derived identities, grounded in recognized technical security guidelines and normative recommendations, and presents a practical validation example in Python code.

Estuve leyendo el artículo sobre lo que se le llama el escándalo Milei, y se me quedaron varias cosas dando vueltas. La idea de fondo es que lo que está pasando en la ANDIS (Agencia Nacional de Discapacidad) –con audios que señalan presuntos sobornos en compras de medicamentos, vinculaciones con personas cercanas al poder, y la sospecha de que el Presidente estaba al tanto– no es algo aislado, según lo que plantea la nota. Lo que más me quedó resonando es cómo ese caso pone en evidencia un problema estructural: cuando un gobierno promueve el Estado mínimo, reduce los controles, flexibiliza las compras, y pone gente de confianza en áreas que deberían ser muy reguladas, se crean espacios para que pase lo que parece estar pasando ahora: decisiones opacas, favorecimientos, y amiguismos. También me pareció importante lo que comentan sobre cómo la opinión pública ya está reaccionando: Milei pierde imagen, se diluye algo de la confianza, y la corrupción se convierte en una preocupación que supera en importancia a temas como inflación o inseguridad para mucha gente. Esto puede tener consecuencias electorales reales. Al final la conclusión que saco es que este escándalo no debería verse únicamente como una crisis política momentánea, sino como una llamada de atención: si el modelo se basa en un mercado que actúa casi sin barreras, sin supervisión adecuada, entonces lo público termina siendo terreno fértil para los abusos. Si no se recupera capacidad del Estado, reglas claras, transparencia y verificaciones independientes, todo lo que se recorta en nombre de la eficiencia puede costar muchísimo, sobre todo para quienes dependen de servicios esenciales como salud y discapacidad.  ( 6 min )

Fast-forward to today and… well, how’s that monkey JPEG portfolio doing? I’ll be real: I bought into some of the hype too. I once let an AI refactor part of a billing system, thinking I was a genius for “outsourcing” grunt work. It passed tests on Friday, and by Monday our staging env was double-charging customers.

Why the “K8s is dying” meme keeps spreading, what teams are actually switching to, and why Kubernetes still quietly runs the internet. “Kubernetes is dead.” If I had a dollar for every time I’ve seen that headline on Hacker News or Twitter (sorry, X), I’d finally cover this month’s EKS bill. Here’s the thing: Kubernetes isn’t dead. It isn’t even limping. It’s quietly orchestrating billions of dollars of production workloads for banks, retailers, and cloud giants. The only thing dying is developer patience when a startup spins up Istio for a blog with 500 monthly visits. This isn’t new. Mainframes? Declared obsolete for 40 years still running Wall Street.

A month of coding the “Japanese way” showed me why tiny daily improvements beat heroic rewrite. Midjourney If Silicon Valley’s motto is “move fast and break things,” Japan’s quiet reply is “move carefully, and let it last.” I thought I knew how to code cleanly. I’d read Clean Code, memorized half the Google style guide, even argued in Slack about tabs vs. spaces (sorry, still tabs). Then I wandered into a Japanese open-source repo and it felt like I’d walked into a completely different world. The README wasn’t two lines of npm install && npm run dev. It was an essay.

Go and C# developers both like to claim that their language is more memory efficient. But which one really has the edge? The truth is: both are right, depending on the scenario. One of Go’s design goals is high concurrency performance, and its memory strategy reflects that. Go’s concurrency unit, the Goroutine, is extremely lightweight. A Goroutine’s initial stack size is about 2KB, compared to 1MB or more for a typical OS thread. This means Go can spawn thousands of concurrent tasks with minimal memory cost, making it ideal for back-end services that handle massive numbers of connections (API gateways, microservices, etc.). Go encourages the use of value types (structs). When passed between functions or stored in collections, they are stored contiguously in memory, reducing fragme…  ( 8 min )

Meta’s Ray-Ban glasses are flashy, but the Neural Band’s EMG input and open-SDK potential could reshape computing if privacy doesn’t kill it first.

Continuing from Day 008 Progressive Enhancement. enhancing or improving CSS by using newer CSS syntax in web page design. I like how Keith puts it when talking about CSS: The language is intentionally designed to be both forward and backward compatible, and it provides you with the tools to keep your code working in both old and new browsers at the same time. Forward compatibility means that old browsers can handle newer CSS syntax. In other words, older browsers are “compatible with the future” because they will simply ignore what they don’t understand and use a fallback. A fallback is code the browser relies on if it doesn’t understand the newer syntax, provided the older code is declared. Backward compatibility means that new browsers can handle older CSS syntax. In other words, newer browsers are designed to understand legacy CSS. To understand it better: New CSS code works on an old browser = Forward Compatible Old CSS code works on an old browser = Normal New CSS code works on a new browser = Normal Old CSS code works on a new browser = Backward Compatible Understanding this gives you an advantage in styling web pages that work across most user agents. It’s good practice to keep learning and trying out newer, more efficient ways to write CSS, while still providing fallbacks. That way, users without updated browsers can still experience a functional design. This is basically the essence of Progressive Enhancement. I believe anyone can become a CSS Pro, and therefore I am.  ( 6 min )

"Your SQL query failed. Let me fix that for you." This simple capability transforms LLM-generated SQL from a source of frustration into a reliable system component.

Introduction: Why SAST for C/C++? Static Application Security Testing (SAST) is a foundational practice in modern secure software development. Unlike dynamic or runtime analysis, SAST examines source code without executing it, identifying vulnerabilities early in the development lifecycle when they are cheapest and easiest to fix. While enterprise-grade tools often dominate the conversation, lightweight, open-source alternatives like Flawfinder offer tremendous value. This is especially true for teams working with C/C++, embedded systems, or legacy codebases where simplicity, speed, and zero cost are critical. In this article, we'll apply Flawfinder to a sample C++ program, interpret its findings, and discuss how to integrate it into a development workflow. Why Flawfinder? Flawfinder is a …  ( 9 min )

More connections } As you can see or try to understand, The Matrix is very similar to Blade Runner or Dark City (to some extent), and another film in roughly the same neighborhood would be: Inception is similar to or has connections to The Matrix, Interstellar, and, finally, Memento.

The Problem We All Face // We've ALL written this boring code... const mockUser = { name: "John Doe", email: "john@example.com", age: 25, isActive: true, // ... 50 more fields }; const anotherMockUser = { name: "Jane Smith", email: "jane@example.com", age: 30, // Copy-paste-modify hell continues... }; Sound familiar? Writing test data is: Time-consuming Error-prone Mind-numbingly boring Repetitive across projects The Game Changer What if you could do this instead: // 1.

I have been Vibe coding. Everybody is calling that shit. Yesterday, I was against the trend; now I jump on the wave. But why? What is it all about? When is it appropriate and when is not? I have been using GitHub Copilot for over a year, especially since it was free. I tried Cursor, and Gemini is my best friend. However, this is not vibe coding. At least, this is not working well with AI. I was doing it all wrong. GitHub Copilot is not Vibe coding This quarter, the CEO sent me on a mission: “I’d like you to test every AI tool you can and make a manual for your team. I want the hole agency working with AI. We must be more efficient.” Gemini or ChatGPT is the new Google. It is useful to ask questions, investigate, or improve your ideas. Cursor and GitHub Copilot are developer assistants.

Read this article on Signadot. One of the common challenges when working with GraphQL is managing schema evolution, especially testing changes introduced in a subgraph of a federated API without disrupting baseline traffic. This document presents an approach to address that challenge by combining WunderGraph with Signadot Sandboxes, enabling you to validate schema updates in an isolated environment while preserving baseline reliability. Before we explore how to integrate Sandboxes with WunderGraph, let’s define the baseline environment. We’ll follow the setup described in the WunderGraph Cosmo Cloud Onboarding guide, but adapt it to run on Kubernetes (using a local minikube cluster for this demo). Prerequisites: kubectl and minikube installed A WunderGraph Cosmo account The wgc CLI install…  ( 9 min )

Let's be real for a second. If you're still running retrospectives with sticky notes on a shared screen or, worse, trying to wrangle feedback through Slack threads, you're doing it wrong. Your team deserves better, and more importantly, your retrospectives could be SO much more effective with the right retro tool. I've been through the painful evolution of remote retrospectives, from awkward Zoom calls with shared Google Docs to clunky whiteboards that barely worked. But here's the thing, the right retro tool doesn't just digitize your sticky notes, it transforms your entire retrospective experience. Enter Kollabe, a retro tool that actually makes retrospectives... Fun! 🎉 Most retro tools treat retrospectives like a chore. They give you a digital board, some voting buttons, and call it a…  ( 13 min )

The Question That Started Everything What happens when you feed a recursive system a lie? Not just once, but repeatedly, letting it process its own increasingly corrupted outputs? I spent four months finding out, and the answer is both beautiful and terrifying. I started building what I called "Recursive Contamination Field Theory" (RCFT) - basically a framework to study memory dynamics in systems that eat their own outputs. Like a game of telephone, but the person is only talking to themselves, and we can measure exactly when they start believing their own distortions. Here's the core loop that started it all: def recursive_update(field, memory, alpha=0.3, gamma=0.9): """ The dangerous loop - systems eating their own outputs """ # Current state influenced by memory n…  ( 8 min )

The frontend developers who lived at number 2013, Privet Drive, were proud to say that they were perfectly normal, thank you very much. They believed in separation of concerns - HTML in templates, JavaScript in scripts, CSS in stylesheets. And here I was, breaking all their sacred rules. I was small and skinny for my age, and wore my cousin jQuery's oversized hand-me-downs. My code looked clunky next to him. The year was 2013 - May 29th, to be exact - when Jordan Walke first introduced me to the world at JSConf US. I wore my Sunday best to the conference. The programmers looked skeptical. Some even hostile. To them, I was a step backward. "JSX! Mixing HTML and JavaScript? That's an abomination," they scoffed. Underneath my awkwardness, I had talent. My secret sauce -> always redraw the who…  ( 8 min )

If there's one thing every developer has heard, it's: "first make it work, then optimize". And it's true - you can't write the most performant code in the world if it doesn't actually solve the problem. What Big O Is (in Simple Terms) Main Types of Big O with C# Examples O(1) - Constant Explanation: Time doesn't depend on input size. Pros: Best type of complexity, extremely fast and scalable.  Cons: Not always possible; depends on the problem. Example: Accessing an array element by index: arr[5] O(n) - Linear Explanation: Grows proportionally to the number of items. Pros: Usually acceptable for large inputs.  Cons: Can be slow if the input is huge. Example: Iterating through all items in a list  C# Example: O(n²) - Quadratic Explanation: *Grows quickly due to nested loops.  Cons: **Worst complexity here; not scalable for large inputs. Nested loops  C# Example: / } * Explanation: Grows slowly, even with large inputs. Pros: Very efficient; grows slowly even with large data sets.  Cons: Usually requires data to be specially structured (like a tree or sorted array). Example: Binary search in a sorted array  C# Example: O(n log n) - Linearithmic Explanation: More efficient than O(n²), often used in sorting. Pros: Acceptable for most inputs; great for tasks like sorting.  Cons: Slower than linear or logarithmic, but still scalable. Example: **Efficient sorting algorithms, like MergeSort or QuickSort (average case) var sorted = numbers.OrderBy(x => x).ToList(); Why This Matters In practice, Big O helped me understand that not all code scales well.  Two algorithms can solve the exact same problem, but one stays fast even with millions of records, while the other becomes practically unusable. Knowing this made me start looking at my code differently.  It's no longer just: "does it work?", but also: "will it still work well if the data grows 10x or 100x?".  ( 7 min )

In Azure, a subnet has a single address prefix, a part of your Virtual Network (VNet) address space. This works fine until your workloads outgrow the available IPs. Traditionally, the fix meant creating a new subnet and moving resources, often causing downtime. Now, Azure has introduced a multiple-prefix subnet feature that lets you expand capacity without redeploying. Sometimes, your subnet prefix is too small and doesn’t fit your needs anymore. In many situations, it is not a problem. Think of a subnet as a logical grouping of virtual network interfaces (vNICs) that share the same network policies, like Network Security Groups (NSGs), NAT Gateways, and route tables. Within the same VNet, vNICs can communicate directly, regardless of which subnet they’re in. Adding a new prefix to the VN…  ( 8 min )

Se tem uma coisa que todo desenvolvedor já ouviu é: “primeiro faz funcionar, depois otimiza”. E é verdade, não adianta escrever o código mais performático do mundo se ele não resolve o problema. Mas chega um momento da jornada em que apenas “funcionar” não é suficiente. Foi aí que eu esbarrei na famosa Big O Notation. No começo, parecia um bicho de sete cabeças, cheio de letras e gráficos que não faziam muito sentido. Mas quando comecei a aplicar no meu código, percebi que não era só teoria de faculdade: fazia diferença de verdade no dia a dia. A Big O Notation é uma forma de descrever a eficiência de um algoritmo em relação ao crescimento da entrada de dados. O nome vem de “Order of”, ou seja, a “ordem de crescimento” do algoritmo.

This is a very nuanced post. Apologies if I ramble a little initially, but I think it is essential to describe the nuance before going further. The first argument I often hear for a multi-cloud strategy is cost optimization. The idea is that you can cherry-pick the cheapest services from each provider. While this sounds great on a whiteboard, the reality is far more complex and often more expensive. First, you are now paying for duplicate infrastructure, even if it's just for disaster recovery or failover. You have to account for data transfer costs between clouds, which can be astronomical and are often overlooked in initial planning. Furthermore, you lose the volume discounts and committed-use savings you might have negotiated with a single provider. The engineering effort required to b…  ( 8 min )

Intro When EventBridge delivers messages to its target, there can be many reasons that cause failing to send a message. There can be permission issues, rate limits or the unavailability of the target or even can be a glitch in the AWS itself, just to name a few. No matter what the reason is, it is always ideal to get notified that there is an issue delivering messages and the reason for the failure. In this blog post I will discuss how a dead letter queue can be useful to get notified when the EventBridge fails to deliver messages to its target. Dead letter queues are unsung heroes of the event driven architecture 😀. Those are easy to set up and manage yet greatly improve the resilience of a system. Also it is very cost effective. Let’s see how we can capture the target delivery failure…  ( 8 min )

As a long-time WebStorm user trying to migrate to VSCode (mainly because VSCode seems to integrate better with modern AI tools and extensions), I quickly noticed some differences—especially around Git conflict resolution. While VSCode is powerful and extremely customizable, there are still areas where WebStorm offers a smoother, more feature-rich experience out of the box. In WebStorm, conflict resolution feels more granular. You can manage each line individually: In VSCode, the built-in merge editor works differently. It highlights conflict sections and provides options like “Accept Current,” “Accept Incoming,” “Accept Both,” or “Compare Changes.” However, it applies the choice to the whole conflict block, not line by line. This is faster for simple cases, but less precise if you want fine-grained control: After resolving a merge, it’s often useful to double-check which files originally had conflicts—especially when reviewing your work or collaborating on complex merges. In WebStorm, this is straightforward. The Git log not only shows merge commits but also clearly highlights which files had conflicts during that merge: In VSCode, you can see the list of files changed in a merge commit, but not specifically which ones had conflicts. Even with GitLens, the UI focuses on “modified vs added vs deleted” files. Conflict status isn’t preserved in the UI, so you lose that bit of insight after the merge is completed:  ( 6 min )

Today I received an Upwork job invite titled Experienced Node.js Coder Needed for Bug Fix” It looked normal at first, but a few details didn’t sit right: 💸 Unrealistic budget for a simple bug fix. 📦 The client insisted I download and run a ZIP immediately to “see the error.” 👤 Profile not payment verified and brand-new. Instead of running it, I inspected the archive without executing anything. node/helpers/css.js reads a “CSS” file (public/css/types.txt) and runs it with eval() only on Windows. types.txt isn’t CSS at all—it’s obfuscated JavaScript that extracts hidden ZIPs (js.zip, node.zip, i.zip),and silently spawns Windows executables via cmd.exe /c start. The project even bundles a 7-Zip binary so it can unpack those hidden files locally.**_ That pattern—obfuscation + hidden zips + detached .exe launch—is exactly how a dropper/backdoor works. I’ve flagged the job and reported it to @Upwork Trust & Safety so they can warn others. 🔑 Takeaways for fellow freelancers Never run code from strangers without first looking inside (even on trusted platforms).

React is often called a “Single Page Application” framework, but you might see multiple pages in your UI. How does that work? Let’s break it down. ✨ When people say React apps are Single Page Applications (SPA): The app loads one HTML file from the server, usually index.html. React dynamically renders components inside a root element, without fully reloading the page. All navigation and content changes happen client-side, in JavaScript. 💡 The “single page” refers to one HTML shell, not that your app can’t have multiple views or sections. Even though SPAs are technically one HTML page, users expect different URLs for different views: /home → Homepage /profile → User profile /settings → Settings page Without routing: Navigation would rely on showing/hiding components manually, which is mess…  ( 7 min )

This post covers the fundamentals of subnetting in the AWS console and how to properly subnet your networks. In AWS, subnetting is dividing your VPC (Virtual Private Cloud)network into smaller networks called subnets. A subnet is a network within a network. To properly divide your VPC CIDR block into working subnets you must first understand what CIDR blocks are made up of. CIDR blocks are made up of five numbers, the first four being the routing prefix and the last number with usually has a "/" before the number and it is called a netmask e.g (10.0.0.0/24). Each octet in the routing prefix separated by dots have 8 bit. The net mask tells you how many of the 32 bit routing prefix must be fixed or allocated for the network identifier. So in a /24 net mask the first three octets are fixed and the fourth one can change to give you a group of IP addresses that are consecutive to one another. For this example we will be using an IP address with a /24 net mask. Take the IP dress 10.0.0.0/24 the simple way to calculate the number of available IP addresses here would be Further subnetting of our VPC into a /27 network would mean we have 32 subnets to allocate per subnet which means we can have up to 8 subnets in the VPC. To make sure your subnets do not have overlapping IPs you can configure your IP ranges like this: The fist subnet can have an IP range of 10.0.0.0/27 - 10.0.0.32/27, the second subnet should then have IPs ranging from 10.0.0.33/27 - 10.0.0.64/27 the third subnet follows with would range from 10.0.0.65/27 - 10.0.0.96/27 etc. Each subnet in the /27 network start where the previous one ended. Subnetting is the most crucial part of a cloud infrastructure and knowing how to subnet a network is a crucial skill for a cloud engineer. Learning and writing about this today has deepened my knowledge of subnets and I hope reading this post does the same for you too.  ( 7 min )

To implement Data Concurrency and Read Consistency, Oracle stores transaction metadata in part of the data block header. This area of the block header is called the Interested Transaction List (ITL) and can contain multiple slots. A transaction that wants to acquire a row must occupy an ITL slot in the block header of the block that contains that row. In the slot the database records information such as the Transaction ID (XID), the Undo Block Address (UBA), and the number of rows the transaction has locked in that block. Each slot belongs to a single transaction, and each transaction can occupy only one slot per block. When a transaction ends (COMMIT or ROLLBACK), its ITL slot becomes reusable by other transactions. The size of each transaction slot is about 24 bytes. Note that physical r…  ( 13 min )

Validation, Cleanup, and Wrapping Things Up Properly You made it. The refactor is merged. You didn't break production (hopefully). Now what? A refactor isn't truly done when the code is merged — it's done when you've validated its impact, cleaned up the mess, and learned from the process. Let's go over what happens after the refactor. Compare your "before" and "after" metrics: Metric Before After Result Test coverage 58% 85% ✅ Improvement Average response time 600ms 320ms ✅ Faster Cyclomatic complexity 18 7 ✅ Cleaner logic Bug reports/week 4 1 ✅ More stable If the results don't show improvement: Re-evaluate the refactor goals Check if you optimized the wrong thing Or consider follow-up iterations 💡 Don't assume success — measure it.

Oasis CLI is now officially available on Homebrew, making it easier than ever to install and manage on macOS and Linux. Previously, developers needed to download unsigned binaries or work through manual installation steps. With Homebrew support, you get: One-line installation and updates Signed and verified packages Consistent workflow across Mac and Linux Easier setup for CI/CD pipelines If you already use Homebrew, installation is a single command: brew install oasis Updating to the latest version is just as simple: brew upgrade oasis And if you ever need to remove it: brew uninstall oasis Once installed, you can start interacting with the Oasis stack right from your terminal. For example: # Check your installation oasis --version # Deploy a smart contract to Sapphire oasis tx contract upload ./my_contract.wasm # Interact with an existing contract oasis tx contract call --method myMethod --args '{"key": "value"}' # Query chain state oasis query block The CLI supports workflows for Sapphire (confidential EVM), ROFL (runtime offchain logic), and more. Reproducibility: Homebrew formulas make it easier to lock versions in dev environments. Automation: Simplifies setup in CI/CD pipelines—just brew install oasis in your workflow. Cross-platform consistency: Works the same across macOS and Linux environments. With Homebrew support, the Oasis CLI is now much easier to integrate into daily development. Whether you’re deploying confidential contracts on Sapphire or experimenting with ROFL, you can now install and update your tools with a single command. 👉 Check out the formula here and start building.  ( 6 min )

Aplicações modernas funcionam raramente isoladas. Muitas vezes temos um frontend que lida com a experiência do usuário, e um backend que concentra as regras de negócio e o acesso a dados sensíveis. Neste artigo, vamos construir uma solução que utiliza Next.js como frontend, integrando a autenticação com o Microsoft Entra ID (antigo Azure Active Directory), e um backend em Node/TypeScript que valida tokens JWT emitidos pelo Entra ID antes de liberar o acesso a rotas protegidas. A solução pode ser entendida em cinco passos principais: O usuário acessa a aplicação em Next.js e inicia o login. O NextAuth.js redireciona o usuário para o Microsoft Entra ID. Após a autenticação, o Entra ID retorna um ID Token e um Access Token para o Next.js. O frontend envia o Access Token ao backend, no header…  ( 8 min )

A well-named variable is like a clear sign on a mountain trail—it tells you exactly where you are and where you're going. It carries meaning effortlessly, making your code read like a story that anyone can follow. The best variable names are like good friends—you understand them immediately: # Variables that speak truth user_age = 25 email_address = "sarah@example.com" is_logged_in = True shopping_cart_total = 127.50 # Collections that describe their contents active_users = get_active_users() pending_orders = filter_pending_orders() error_messages = [] Each name reveals its purpose without ceremony. When you see user_age, you know it's a number representing someone's age. When you encounter is_logged_in, you immediately understand it's a boolean flag. No translation required. Short names…  ( 8 min )

trustless and private? Traditional approaches force developers to either hand over control of keys or expose sensitive trading strategies to the chain. zkAGI is addressing this with PawPad, a platform for private trading agents built on the Oasis Protocol. By combining the Sapphire runtime (confidential smart contracts) with ROFL (TEE-based offchain execution), PawPad enables secure, multichain wallet control and encrypted strategy execution—without relying on bridges. Building multichain agents involves several pain points: Key Management: Users must trust that developers won’t misuse private keys. Confidentiality: Onchain execution risks revealing strategies to competitors. Cross-Chain Complexity: Each chain has its own SDKs, account formats, and signing flows. PawPad tackles these issue…  ( 7 min )

NestJS is a progressive Node.js framework for building efficient, reliable, and scalable server-side applications. Combining the best ideas from OOP (Object-Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming), it gives you a fully-architected, batteries-included platform on top of Express (or Fastify). If you’re coming from Angular, you’ll feel right at home with its module/controller/service structure and powerful dependency-injection system. 1. What is NestJS? Wraps a mature HTTP server library (Express or Fastify) Standardizes application architecture around modules, controllers, and providers Leverages TypeScript’s type system for compile-time safety and clear APIs Offers built-in support for things like validation, configuration, and testing npm install -g @nestjs/cli nest new my-app cd my-app Modules @Module({ Controllers @get() — Defines a get request @post() — Defines a post request @Delete() — Delete request @Put() — Put request Here is an example of a simple controller with one get route: @Controller('item') @get() Providers @Injectable() create(item: Item) { findAll(): Item[] { Now that we have defined our service let’s use it in our controller: @Controller('item') @get() Usage Here is a simple example of the OnModuleInit interface: import { Injectable, OnModuleInit } from '@nestjs/common'; @Injectable() The module has been initialized.); Pipes transformation — transform input data to the desired output Usage: import { PipeTransform, Injectable, ArgumentMetadata } from '@nestjs/common'; @Injectable() In this example we check if the metatag we provided isn’t empty and if so we converted the received data to the metatype we defined. Unit tests import { Test } from '@nestjs/testing'; describe('ItemService', () => { beforeEach(async () => { service = module.get(ItemService); }); it('should be defined', () => { expect(service).toBeDefined(); }); });  ( 7 min )

Introduction Model Context Protocol (MCP) servers have revolutionized how AI applications access external tools and data sources. From web browsing with Playwright to documentation search with Context7, MCPs provide a standardized way to extend AI capabilities beyond their training data. However, as the MCP ecosystem grows, managing multiple servers becomes increasingly complex. Each MCP server typically requires separate installation, configuration, and maintenance across different clients like Claude Desktop, Cursor, or Claude Code. This fragmentation creates several pain points: Configuration sprawl: Each client needs individual server configurations Dependency conflicts: Different servers may require conflicting Python versions or packages Resource overhead: Multiple server process…  ( 10 min )

Desenvolvedores que atuam no ecossistema blockchain frequentemente enfrentam um desafio comum: como obter dados do mundo real, como preços de ativos, de forma segura e confiável dentro de uma aplicação descentralizada.

Have you ever wondered how JavaScript/Node.js efficiently handles complex requests despite being single-threaded? What happens when a CPU-intensive task runs on your backend, affecting other requests? Is there a way to run these tasks separately and simultaneously? In this article, we'll explore how to achieve this by understanding single-threading vs. multi-threading and how the Worker Threads module can help improve Node.js performance. SIngle-threaded JavaScript: We all know that, unlike languages like C++, C#, and Java, which support multi-threading, JavaScript is single-threaded because it was originally built for client-side scripting to make web pages interactive and run only in the browser. But over time, we can now run JavaScript on the server thanks to Node.js. Due to this sing…  ( 13 min )

I’m starting a new series of blogs where I’ll share the tips and tricks I use to optimize games for better FPS. I’ll only share the techniques that I learn myself or actually use in my projects. Today, let’s talk about one of the biggest game optimization techniques in Unity: Object Pooling. For reference, here’s a scenario from one of my games. I was working on a bombing and cannon fire mechanism. Bombs drop from above at fixed intervals but from random locations, and cannons fire cannonballs at fixed intervals sequentially. I wrote a script where I assigned the bomb/cannonball prefab, instantiated it at runtime, and fired it. Once the bomb/cannonball touched anything, it would self-destruct using the Destroy method. On PC, this worked fine — I was getting around 200 FPS. But when I built…  ( 9 min )

Converting images to PDF sounds simple, but when you try to make it work for everyone (desktop, mobile, different formats, large files), you realize it’s a real challenge. In this post, I’ll share how I built onlin3.net — a free tool that allows anyone to upload images (JPG, PNG) and turn them into a clean PDF file. For this project, I kept things simple but powerful: PHP for the backend. mPDF for generating PDFs. Bootstrap for a clean, responsive UI. This allowed me to focus on solving the actual problem instead of reinventing the wheel. The first step was to handle multiple image uploads safely. php if ($_SERVER['REQUEST_METHOD'] === 'POST' && isset($_FILES['images'])) { $files = $_FILES['images']; foreach ($files['tmp_name'] as $file) { $image = imagecreatefrom…  ( 7 min )

I’ve just started my journey into the Linux world. Until recently, I only used Windows, but I kept hearing about Linux being free, secure, and great for developers. Last week I finally decided to install it and see what the hype is about. In this post I’ll share: Why I chose Linux How I installed it The first commands I learned My tips for other beginners I wanted a system where I could: Learn real command-line skills Use free and open-source software Run tools like Docker more easily than on Windows After some research I picked Ubuntu because it’s beginner-friendly and has lots of tutorials. Other popular beginner choices are Linux Mint and Fedora. I downloaded the ISO from ubuntu.com, used Rufus to create a bootable USB, and installed Ubuntu alongside Windows (dual boot). The installer walked me through the process step by step. Once I logged in, I opened the Terminal (Ctrl+Alt+T) and tried these: pwd # show current directory ls # list files cd # change directory sudo apt update && sudo apt upgrade # update system packages ` Learning these gave me a sense of control over my system. Don’t be afraid of the terminal — start small. Bookmark the Ubuntu documentation. Join communities (r/linux on Reddit, forums) to ask questions. Make a list of what you want to achieve (e.g. install VSCode, set up Git, try Docker). Switching to Linux felt scary at first, but it’s been fun and empowering. I’m still learning, but already I feel like I understand my computer more deeply than before. If you’re thinking of trying Linux, go for it! And if you’ve recently started, what was the first thing you learned? I’d love to hear your tips in the comments.  ( 6 min )

In the evolving landscape of artificial intelligence, the Model Context Protocol (MCP) has emerged as a crucial primitive for enabling sophisticated interactions between AI models and external systems. Darren, the creator of Nanobot by Obot.ai, presents a compelling vision where MCP forms the bedrock for building powerful, interactive agents. His work is driven by the conviction that an AI model, coupled with an MCP server, provides the essential components for nearly any agentic endeavor.

1) What the EVM is and why it matters The Ethereum Virtual Machine (EVM) is the execution environment that runs smart contracts and applies state changes. It defines opcodes, gas accounting, and transaction semantics. EVM compatibility means: Developers keep using Solidity, Hardhat, Foundry, MetaMask, Blockscout, and other Ethereum tools without rewriting code. Existing patterns for logs, events, ABI encoding, and receipts behave the same, so indexers and wallets integrate cleanly. Migration cost is low because applications do not need a new VM or custom SDKs.

The Linux file permissions were very complex for me at the beginning. In this article, we’ll break down Linux permissions in detail. I'll try to make it as simple as possible. Linux is a multi-user system. Even on your personal computer, system processes, services, and your own account interact with files. Permissions ensure: Sensitive files can’t be read or edited by the wrong users. Scripts and binaries are only run when explicitly allowed. System stability and security are preserved. Every file and directory in Linux can have three kinds of permissions: Read (r) → View the file contents or list directory contents. Write (w) → Modify or delete the file, or create/remove files in a directory. Execute (x) → Run the file as a program/script, or enter a directory. Permissions are assigned to…  ( 7 min )

The script first ensures that addEventListener is in globalThis. But in means as own property or anywhere on the prototype. So let's find it on the prototype by iterating down. We throw when found. addEventListener. alert and it works. Normally, when you run: let w = globalThis while (w) { if (Object.hasOwn(w, 'addEventListener')) { console.log(`${w} has addEventListener`) } else { console.log(`${w} does NOT have addEventListener`) } w = Object.getPrototypeOf(w) } the output is: [object Wind…  ( 7 min )

Hey Hackspire '25 innovators! The air is buzzing, the coffee machines are warming up, and your keyboards are just waiting to bring ground-breaking ideas to life. As we gear up for what promises to be an unforgettable event, we wanted to share a project idea that we believe embodies the spirit of Hackspire: innovation for impact. This year, let's turn our collective coding prowess towards a challenge that truly matters: public health in vulnerable communities. The Challenge: Water-Borne Diseases in Rural Northeast India Imagine a scenario where simply drinking water can lead to serious illness. This is a harsh reality for many rural and tribal communities in Northeast India. Water-borne diseases like cholera, typhoid, and diarrhea are prevalent, especially during the monsoon season. Why? Contaminated water sources, inadequate sanitation, and the sheer remoteness of villages make it incredibly difficult for health workers to monitor and respond to outbreaks quickly. The lack of real-time data means health officials are often playing catch-up, leading to preventable suffering and even loss of life. This isn't just a health problem; it's a socio-economic one, hindering progress and well-being. Our Vision: A Software-Only Smart Health & Early Warning System We believe that with the right software, we can empower communities and health officials to get ahead of these diseases. Our project idea proposes a Smart Community Health Monitoring and Early Warning System – designed specifically for the unique challenges of rural Northeast India, and crucially, built entirely on software. What does "Software-Only" mean for us? It means no expensive, fragile IoT sensors to deploy in remote, harsh terrains. It means leveraging existing community structures and tools, empowering health workers with intelligent digital tools they can use with their smartphones.  ( 6 min )

Principal Component Analysis, PCA for short, is a bit of a “deep” topic in machine learning. By deep I mean that you need to know about clusters, covariance, and then you learn about principal component analysis – who knows what else is there after PCA. Learning about PCA is like learning about glucose: you can’t really understand glucose unless you already know what sugar is. I say this to emphasize that PCA is a challenging concept to grasp without some prior knowledge. That being said, here’s what PCA means. When creating clusters of data, we often deal with multi-dimensional data points. For me it’s easy to picture a point in a 2D axis (x, y), or even in 3D (x, y, z). But once it goes beyond 3D into 4D or more, it becomes nearly impossible to mentally visualize. Visualizing the data itself is already hard — now imagine trying to rotate or move one of these high-dimensional points. At that point, I just trust the math that it works. Enough venting. So, what is PCA? PCA comes from simplifying the covariance matrix. What is a covariance matrix? A covariance matrix is a 2D table that shows how the variance of one feature relates to another. For example, suppose we have a dataset with the following features: The covariance matrix for these might look like this (values are illustrative, not from real data): • The diagonal values (25.0, 9.0, 30.0, 40.0) are the variances of each feature. This table is already hard to interpret with just 4 features. Imagine 100+ features — the relationships get too complex to reason about directly. Why PCA? That’s where PCA comes in. PCA finds the principal components — the directions in which the data varies the most. By rotating the data into this new coordinate system, we can: In essence, PCA transforms the messy covariance relationships into a simpler structure. Instead of asking “how does feature A affect feature B,” PCA lets us ask, “what combination of features explains most of the variation in this dataset?”  ( 7 min )

Day 6 of My JavaScript Visual Series 📚✨ 💡 Arrow Function vs Normal Function in JavaScript – Why It Actually Matters in Interviews. As a beginner, I used to think both functions are the same. But here's what interviewers love to ask the difference in how "this" behaves in both! 🔹 Arrow Function: const obj = { name: "Azaan", sayHi: function () { console.log("Hi", this.name); // Works ✅ }, greet: () => { console.log("Hello", this.name); // Undefined ❌ } }; Fun Fact : Arrow function is also called fat arrow function. A couple of days ago, I was debugging a login feature in my app. Everything seemed perfect... except it kept saying "Invalid Password" even for correct ones. // ❌ Wrong: 'this' doesn't refer to the document userSchema.methods.comparePassword = (inputPassword) => { return bcrypt.compare(inputPassword, this.password); }; // ✅ Correct: 'this' refers to the Mongoose document userSchema.methods.comparePassword = function (inputPassword) { return bcrypt.compare(inputPassword, this.password); };  ( 6 min )

What is React's useTransition Hook? The useTransition hook in React allows you to mark certain state updates as "transitions," which means they can be performed in the background without blocking the main UI thread. This helps keep your app responsive during potentially slow or non-urgent updates, like loading new content or switching views. It returns an array with two values: isPending: A boolean that indicates if there's an ongoing transition (true while the update is pending). startTransition: A function you wrap around your state update to mark it as a transition. You call useTransition at the top level of your component, similar to other hooks like useState. useTransition? The main purpose is to improve user experience by preventing the UI from freezing or showing unwanted loadin…  ( 7 min )

"Please fix this mess." Three words that can turn a simple code review into a team morale disaster. Sound familiar? Code reviews aren't just technical checkpoints—they're psychological minefields where egos, emotions, and expertise collide. The difference between feedback that builds and feedback that breaks often comes down to understanding the human side of code collaboration. Every line of code represents hours of problem-solving, creative thinking, and mental effort. When developers submit code for review, they're not just sharing logic—they're sharing a piece of their professional identity. Research shows that conflicts during code reviews are common, but teams that handle them constructively see significant improvement in both code quality and team dynamics. The key isn't avoiding …  ( 8 min )

Prompt engineering is evolving fast, and while TAG and RISE are powerful tools, there are other frameworks that can help you get even better results from AI models. In this post, we’ll explore two lesser-known but super useful models: RTF and BAB. RTF stands for: Role: Define the AI’s persona or function. Task: Describe the task you want it to perform. Format: Specify the format of the output. Prompt: Act as a UX designer. Create a checklist for onboarding screens. Show me in bullet points. Role: UX designer Task: Create a checklist Format: Bullet points This framework is great when you want clarity and structure in the output. BAB stands for: Before: Explain the current situation or problem. After: Describe the desired outcome. Bridge: Ask the AI to create a solution that connects the two. Prompt: Before: I struggle to stay focused while coding. After: I want to work in 90-minute deep focus sessions. Bridge: Suggest a daily routine and tools to help me get there. BAB is perfect for problem-solving, goal setting, and behavioral change prompts. Use Case RTF BAB Structured output ✅ ❌ Role-based tasks ✅ ❌ Personal development ❌ ✅ Problem-solving ❌ ✅ Creative formats ✅ ✅ RTF and BAB are great additions to your prompt engineering toolkit. Whether you're building apps, writing content, or just trying to get better answers from ChatGPT, these frameworks help you guide the AI more effectively. Try mixing them with other techniques like few-shot prompting or chain-of-thought reasoning for even better results. Happy prompting! 🚀  ( 7 min )

The strictMode parameter in TSDoc has been clarified: It defines the baseline r…  ( 7 min )

Running OCR for Persian text is tricky. Unlike English, Persian (and Arabic) scripts are right‑to‑left, letters change shape based on position, and there are fewer open‑source datasets available. In this post, we’ll build a custom OCR pipeline using YOLO for text detection and CRNN for character recognition. Why YOLO + CRNN? YOLO is great at detecting objects — here, the objects are text regions. CRNN (Convolutional Recurrent Neural Network) is ideal for sequence recognition like text. Combined, they form a two‑stage pipeline: detect → crop → recognize. Preparing the Dataset For Persian OCR we need two datasets: Detection dataset (for YOLO): images with bounding boxes around words or lines. Recognition dataset (for CRNN): cropped images of words/lines with their correct text. You can: Use …  ( 7 min )

Over the past few weeks, I’ve been diving deep into real-time performance monitoring for our platform. It started with analyzing Round Trip Time (RTT) — the total time for a request to leave the client, hit our servers, and return with a response. Monitoring RTT gave us the first insight into end-to-end latency, helping us identify whether delays came from the client, network, or backend. Next, we built a custom query to track Timeout and Cancelled Transactions. The idea was simple: some transactions never finish properly, and without surfacing this metric, they remain hidden behind average response times. By separating these failed interactions, we could measure how often users abandon requests or face slow services — a critical signal for reliability. We didn’t stop there. Rendering Time became another key metric. Measuring frontend rendering duration helped us spot performance bottlenecks after the backend response arrives. It turns out, a fast API is not enough if the UI takes forever to paint meaningful content. We also added visibility into Failed Resource Loads — things like missing scripts, broken images, or third-party calls silently failing in the background. Tracking these issues revealed UX problems that standard error metrics often miss. On top of this, we experimented with custom dashboards, big number widgets for KPIs, threshold-based alerts in Sentry, and trend tables for historical analysis. Each feature brought a new layer of observability, from real-time incident detection to long-term optimization. What I loved about this journey is how each metric unlocked a different perspective: latency, reliability, frontend performance, and user experience — all connected. The result is a monitoring setup that’s not just reactive but proactive and actionable.  ( 6 min )

During the widespread AI revolution, new ideas are easy to come by—but "technology with a heart" that actually works needs something to keep it grounded. For me, that grounding came from real moments with my wife. She’s both a vet and a dedicated animal lover: how focused she is when treating hurt stray cats late at night, how worried she gets when finding foster homes for abandoned puppies, and how helpless she sounds when she says, "One person can’t rescue that many animals"—these small daily moments made me ask: Can AI help spread kindness, so more people can join in rescuing stray animals? As someone who works with technology, I’m used to breaking down problems step by step. The main problems in stray animal rescue are basically two things: "not enough shared information" and "hard t…  ( 11 min )

Preparing for frontend interviews was a nightmare for me. There is just so much resources with 500+ questions and so many topics to cover. The range of frontend interviews today is wild. You can be asked anything from CSS, JS, Performance, Networking, Accessibility, Browser APIs, System Design, and more... Before every frontend interview I use to feel overwhelmed. It took me months before feeling even remotely ready to start applying. The imposter syndrome was just at it's peak. It's not about more and more questions but right set of less questions. “I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.” - Bruce Lee Sounds familiar? I've been there, but I've also sat for multiple frontend interviews in many service and product companies. And noticed a pattern, in every interivew I was more or less asked the same set of concepts just with different variations. On the surface the questions looked different but deep down it was the same old concepts which can be answered easily if you understand concepts like closures, promises, performance, e.t.c. Hence I built a list of the smallest set of questions which covers all important concepts and helps me preapre quickly before a frontend interview. Now, I've decided to publicaly share my list with great explanations, examples, and visuals for FREE.

As developers, we love building things. But let’s be honest — spending hours managing cloud infrastructure, debugging misconfigurations, or fixing scaling issues isn’t the most exciting part of our job. The cloud gives us flexibility, but it also brings complexity. That’s where Managed Cloud Services come in. Instead of babysitting servers and pipelines, you can offload monitoring, security, and optimization to experts — while you focus on writing code and shipping features. The Problem: Cloud Complexity Is Real Cloud adoption has skyrocketed. Most teams are now using multi-cloud environments (AWS, Azure, GCP), containers, Kubernetes, and CI/CD pipelines. Sounds great, right? Until you hit: Unexpected cloud bills Security misconfigurations Slow deployments Struggling with compliance req…  ( 7 min )

Day 8 of my LeetCode streak 🚀 Today’s problem was 165. Compare Version Numbers — a neat string parsing challenge where the tricky part isn’t the logic itself, but handling all the little details: Ignoring leading zeros ("01" = "001") Treating missing revisions as 0 ("1.0" = "1.0.0") Comparing uneven revision lengths I solved it in JavaScript by splitting the version strings into arrays, comparing each part as integers, and defaulting to 0 when one version runs out of parts. Even on a distracted day (hello, Twitter doomscrolling 😅), keeping the streak alive matters. 👉 Full breakdown with code and reflections on my blog: https://nitinahirwal.in/posts/165-CompareVersionNumbers On to Day 9! 🚀 LeetCode #JavaScript #100DaysOfCode  ( 6 min )

In one of my older writings, I argued that “asking the right question” was the golden key to getting quick and useful answers from people. Back then, developer communities, forums, and Telegram groups were the holy grounds where our questions lived. Everyone had Google, but the real magic was asking the right people in the right way. Ask poorly, and you’d either get mocked or dismissed with: “Dude, do your own research first.” Today, things are different. Instead of bad-tempered humans, we now face an always-eager, sometimes confused AI. Large Language Models (LLMs) like ChatGPT have rewritten the rules of the game.

Hi Dev Community, I'm Nauman! I’m currently learning frontend development in Bahawalpur, Pakistan, and this is my story—raw, real, and still unfolding. I didn’t come from a tech background, but I’ve always been curious about how websites work behind the scenes. That curiosity led me to enroll in a web development course at Corvit BWP, and it’s been a rollercoaster ever since. JavaScript hit me like a storm—especially asynchronous concepts like callbacks and Promises. I remember staring at code, wondering why things weren’t working, feeling stuck and overwhelmed. But I didn’t give up. I started asking questions, breaking problems into tiny pieces, and using analogies to make sense of the chaos. Slowly, things began to click. I realized I learn best through real-world examples, visual explanations, and hands-on practice. I started solving small challenges, building mini-projects, and writing down what I understood. That’s why I’m here on Dev.to—to share what I’ve learned in a way that helps others who might be facing the same confusion. I want to turn my learning into something useful for others. My goal is to write beginner-friendly blogs that simplify tough topics, especially for those who feel lost in callback hell or tangled in JavaScript logic. If my posts can help even one person feel more confident, that’s a win. I’m exploring modern tools like Next.js and MongoDB, and I’m excited to share tutorials, breakdowns, and personal insights as I grow. I believe learning is a journey, not a race—and I’m here to walk it with you. Thanks for reading. Let’s build, learn, and grow together.  ( 6 min )

Introduction Artificial Intelligence (AI) is transforming how we interact with technology. Instead of hard-coding logic for every feature, developers can now offload tasks like summarization, reasoning, and content generation to Large Language Models (LLMs). Claude, created by Anthropic, is one of the newest and most powerful AI assistants available today. It competes with models like OpenAI’s GPT, but with a focus on safety, long context handling (up to 200K tokens), and strong reasoning abilities. In this article, I’ll show how Flutter, a cross-platform framework for mobile development, can integrate with Claude’s API to create AI-driven mobile applications. Why Use AI in Mobile Apps? Mobile users generate and consume text constantly — notes, emails, chats, documents, and more. Embedding…  ( 10 min )

Three months ago, I discovered a tool that completely transformed my SQL workflow. Here's my brutally honest review of the MSSQL extension for VS Code. We've all been there. You're in the zone, cranking out application code, when suddenly you need to check something in the database. Alt-tab to SSMS, wait for it to wake up from hibernation, click through a dozen dialogs to get connected, and boom—your coding flow is dead. I used to lose at least 30 minutes a day to this context switching nightmare. Until I found something that changed everything. The MSSQL extension for Visual Studio Code isn't just another database tool—it's a complete paradigm shift. Instead of forcing you to leave your development environment, it brings the database directly into your code editor. And honestly? It works …  ( 9 min )

Introduction Running Nginx on a public server without proper hardening is a recipe for abuse. Two of the most effective, low‑maintenance defenses are TLS encryption and Fail2Ban. TLS protects data in transit, while Fail2Ban automatically bans IPs that show malicious behavior (e.g., repeated 404s or brute‑force login attempts). This tutorial walks an SRE through a practical, step‑by‑step hardening of an Ubuntu 22.04 Nginx instance. TLS eliminates eavesdropping and man‑in‑the‑middle attacks. Modern browsers also flag non‑HTTPS sites as insecure, hurting user trust. Fail2Ban watches log files for patterns that indicate attacks (failed logins, repeated 404s, etc.) and adds temporary firewall rules to block the offending IPs. Together they address both data confidentiality and automated abuse…  ( 8 min )

Mastering Session Management: The Cornerstone of Web Security Introduction In the realm of web security, session management is often the unsung hero. While encryption and authentication grab headlines, how a web application manages user sessions can make or break its security posture. Sessions are the threads that weave a user's journey through a website, maintaining state and identity across multiple requests. However, if not handled properly, sessions become a gateway for attackers to hijack accounts, steal sensitive data, or impersonate users. Understanding Sessions and Their Importance A session represents a semi-permanent interactive information interchange between two or more communicating devices, typically a user and a web server. HTTP is stateless by design, so sessions help maint…  ( 8 min )

Introduction So when it comes to memory management there are two terms you really need to know, the stack and the heap. The stack is a region of memory that stores temporary data that is only needed for a short period of time. It operates in a last-in, first-out (LIFO) manner, meaning that the most recently added data is the first to be removed, as the name suggests. Basically imagine a stack of plates, if you wanna remove one plate you remove the top one, remove the middle plate and disaster awaits in this analogy. The stack is typically used for storing function parameters, local variables, and return addresses. It is fast and efficient because it has a fixed size and does not require dynamic memory allocation. The size of the stack is usually limited, and if a program tries to use mor…  ( 14 min )

In the early days of microservices, REST APIs became the default way for services to talk to each other. They’re simple, predictable, and well-understood. But as systems grow, REST starts showing cracks: latency, bottlenecks, and brittle dependencies. That’s where asynchronous messaging with tools like Kafka, RabbitMQ, or Azure Service Bus takes the lead. REST APIs force a request–response relationship. If Service A calls Service B, A must wait until B replies. Messaging flips this. A just sends a message and moves on. B (and even C, D, E…) can consume it when ready. 👉 This decoupling makes systems more resilient—one slow service doesn’t break the whole chain. With REST APIs, the producer is in push mode. The caller must hit the server directly, regardless of whether that server is busy, …  ( 7 min )

Multithreading is the process of executing multiple threads simultaneously. A thread is the smallest unit of execution. Java provides strong multithreading support via the Thread class and Runnable interface. It helps in better CPU utilization and improved application performance. There are two main ways to create a thread in Java: a) Extending the Thread Class class MyThread extends Thread { public void run() { System.out.println("Thread running using Thread class!"); } } public class ThreadDemo { public static void main(String[] args) { MyThread t1 = new MyThread(); t1.start(); // Start the thread } } b) Implementing the Runnable Interface class MyRunnable implements Runnable { public void run() { System.out.println("Thread running using Runnable interface!"); } } public class RunnableDemo { public static void main(String[] args) { Thread t1 = new Thread(new MyRunnable()); t1.start(); } } A thread passes through these states: New → Runnable → Running → Waiting → Terminated New: Thread object created but not started. Runnable: Thread is ready to run but waiting for CPU scheduling. Running: Thread is currently executing. Waiting/Timed Waiting: Thread is paused temporarily. Terminated: Thread has finished execution. start() → begin thread execution run() → contains the logic of the thread sleep(ms) → pause thread for given milliseconds join() → wait for a thread to finish isAlive() → check if thread is running When multiple threads access a shared resource, race conditions may occur. synchronized keyword ensures that only one thread can access a resource at a time. Threads allow concurrent execution. Two ways to create threads: Thread class & Runnable interface. Use synchronization to prevent race conditions. Multithreading is widely used in games, web servers, and real-time applications.  ( 6 min )

Next.js App Router defaults all components to Server Components. The "use client" directive marks a file as a Client Component. Placed at the top of a file: "use client"; Tells Next.js: render this component on the client (browser). Without it → the file stays a Server Component. // Button.tsx "use client"; export default function Button() { return alert("Clicked!")}>Click me } Without "use client", this would break: event handlers & useState only work in the browser. Next.js defaults to Server Components for speed & smaller bundles. "use client" is an escape hatch when you need client-only features. You need "use client" if you use: React hooks: useState, useEffect, useRef Event handlers: onClick, onChange, … Browser APIs: localStorage, window, document Client-only libraries: Chart.js, React-Quill, etc. Next.js scans for "use client" at build time. That file + its imports → shipped as JS bundle to the browser. Server Components are stripped to HTML + serialized props. Server Components can import Client Components. Client Components cannot import Server Components. // page.tsx (Server Component) import Button from "./Button"; export default function Page() { return ( Hello // Client-side, interactive ); } Default = Server Component (fast, no client JS). Add "use client" only where you need state, events, or browser APIs. Sprinkle sparingly → keep most of your tree on the server. ⚡ "use client" is the switch that brings React interactivity into your Next.js App Router components.

Java 8 introduced functional programming concepts to the language, making code more concise, readable, and powerful.

AbortController is the standard way to cancel async work in modern JavaScript. It pairs with AbortSignal, which you pass to tasks so they can stop immediately. Create a controller → pass controller.signal to your async work. Call controller.abort(reason?) to cancel; consumers see an AbortError (or signal.reason). Works with fetch, streams, and your own functions. const c = new AbortController() const resP = fetch('/api/data', { signal: c.signal }) // later... c.abort('user navigated away') try { await resP } catch (e) { if (e.name === 'AbortError') /* ignore */ } reason support) const c = new AbortController() const { signal } = c signal.aborted // boolean signal.reason // any (why it was aborted) c.abort(new DOMException('Timeout', 'AbortError')) // or: c.abor…  ( 8 min )

1. Stack (LIFO – Last In, First Out) A Stack follows the principle of Last In, First Out (LIFO). Think of a stack of plates: the last plate placed on top is the first one to be removed. Common Methods in Stack: push() – add an element pop() – remove top element peek() – see top element without removing isEmpty() – check if stack is empty Example Code (Stack Demo): import java.util.Stack; public class StackDemo { public static void main(String[] args) { Stack stack = new Stack(); stack.push(10); stack.push(20); stack.push(30); System.out.println("Top element: " + stack.peek()); // 30 System.out.println("Removed: " + stack.pop()); // 30 System.out.println("Is stack empty? " + stack.isEmpty()); } } 2. Queue (FIFO – First In, First Out) A Queue follows the principle of First In, First Out (FIFO). Think of a ticket counter queue: the first person in line is the first to be served. Common Methods in Queue: offer() – add element poll() – remove front element peek() – see front element isEmpty() – check if queue is empty Example Code (Queue Demo): import java.util.LinkedList; import java.util.Queue; public class QueueDemo { public static void main(String[] args) { Queue queue = new LinkedList(); queue.offer(10); queue.offer(20); queue.offer(30); System.out.println("Front element: " + queue.peek()); // 10 System.out.println("Removed: " + queue.poll()); // 10 System.out.println("Is queue empty? " + queue.isEmpty()); } } Stack is best when you need reverse order processing (Undo operations, DFS, expression evaluation). Queue is best when you need sequential order processing (Task scheduling, BFS, request handling).  ( 6 min )

Internationalization (i18n) is the blueprint for global software. At its heart lies a deceptively simple element: the translation key. Your team's approach to naming these keys isn't a minor detail—it's a foundational architectural decision. A poor strategy creates "i18n debt," a silent tax on every future feature that slows development and inflates costs. A great one ensures longevity and streamlines collaboration for years to come. Think of an i18n key not as a variable, but as a stable, multi-party contract between three stakeholders: Developers: They need a predictable interface to retrieve text. The key should offer clues about a string's purpose, reducing the need to constantly jump between the codebase and translation files. Translators: The key is often their first and most impor…  ( 12 min )

As developers and designers, we've all been there. You're working on a new feature, and you need to use the brand's primary color. You open the inspector, find a button that looks right, and copy the hex code: #3B82F6. A week later, another developer does the same but samples it from a slightly different banner and gets #3B83F7. Individually, these tiny inconsistencies are harmless. But they accumulate. Over time, your application's UI becomes a patchwork of "almost-right" values, leading to a messy user experience and a maintenance nightmare. This is the problem that Design Tokens solve. At their core, design tokens are a methodology for managing your design decisions.

Serverless architecture has revolutionized how we build applications, but it comes with a well-known Achilles' heel: managing state. For stateless functions, it’s a dream. But as soon as your application requires real-time collaboration, live presence, or persistent chat, you enter a world of complexity. How do you manage WebSocket connections when your functions are ephemeral? The traditional workarounds are often complex and costly. You might find yourself managing sticky sessions on load balancers or bolting on a separate stateful service like Redis just to handle pub/sub and connection mapping. This adds significant operational overhead, undermining the core promise of serverless. At Vaultrice, we faced this exact dilemma. We needed to build a global, low-latency, and strongly-consiste…  ( 8 min )

React Native has become one of the most popular frameworks for building cross-platform mobile applications. It allows developers to write apps in JavaScript or TypeScript and run them on both iOS and Android with near-native performance. But when you start building your first project, you’ll face a crucial decision: Expo vs Bare workflow in React Native. This choice directly impacts how you develop, configure, and deploy your application.

Wallet onboarding solutions have improved significantly over the last couple of years. While Dynamic.xyz has been a popular option, there are some differences in behavior across platforms that are worth noting. One example is how wallet disconnections are handled in MetaMask. In @dynamic-labs/sdk-react-core@4.32.0, the useIsLoggedIn() hook does not update to false when disconnecting a wallet. This behavior is noticeable not just in code but also on the Dynamic.xyz demo website, where disconnecting the wallet does not log out the user automatically. In contrast, both Privy.io and Web3Auth demos handle disconnects as expected, updating the state and logging the user out when the wallet is disconnected. Developed by the Metamask team. Offers reliable wallet disconnection handling. Supports social login flows alongside decentralized wallets. Provides cross-platform support including browser, mobile, and Unity. Developed and backed by Stripe. Handles wallet disconnections reliably. Supports account abstraction and embedded wallets. Focuses on privacy-first authentication and encrypted data management. From a personal perspective, backing by well-known teams adds confidence in terms of long-term support and reliability. Feature Dynamic.xyz Web3Auth Privy.io Wallet disconnect sync Does not update Yes Yes Social login Limited Yes Yes Account abstraction Partial Optional Default Reliability Generally good Strong Strong Backed by popular teams Medium Metamask team Stripe All three platforms offer wallet onboarding capabilities, but Web3Auth and Privy.io provide additional confidence with reliable disconnect handling and backing from prominent teams. They are favorable choices if you want consistent user experience and support for both social and decentralized login flows. Dynamic.xyz Demo | Web3Auth Demo | Privy.io Demo  ( 6 min )

Unit Of Work.. What is it ? The Unit of Work pattern is a design pattern used to group multiple operations (usually repository calls) into a single transaction. It ensures that either all operations succeed or none are applied, maintaining data consistency. It usually works alongside the Repository pattern, which abstracts data access logic. As I said it can work with repository patten, I will keep the code fairly simple rather than over-complicating it with generic repository. // Models/Product.cs public class Product { public int Id { get; set; } public string Name { get; set; } public decimal Price { get; set; } } // Models/Order.cs public class Order { public int Id { get; set; } public int ProductId { get; set; } public DateTime OrderDate { get; set; } } //…  ( 8 min )

In this blog, we’ll walk through how our Angular application is architected to work with a dynamic CMS setup using a custom library that acts as the bridge between Optimizely CMS and frontend rendering. We’ll explore the folder structure, routing flow, component loading, and how the** dynamic component** architecture works behind the scenes. Our Angular application is organized into three main folders: 1. DropComponents Contains all components that are dropped via CMS into the PageComponents array or the Blocks drop in CMS Content area. These components are dynamically rendered using a custom directive provided by our Angular library. 2. GlobalComponents Contains global UI components such as Header and NotFoundComponent (404 page) etc. 3. Pages Contains route-based page components. Include…  ( 13 min )

When developing modern applications, it’s common to hit a roadblock because the real backend service isn’t ready, or you need to test against multiple APIs at once. That’s where a mock server comes in: a lightweight server that returns fake data and files to mimic the behavior of your real backend. Python is an excellent choice for building mock servers because: It ships with a built-in HTTP server. It has lightweight frameworks like Flask and FastAPI. It can scale from a quick one-liner to a production-like simulation. In this guide, we’ll cover all Python-based options — from serving static files, to full CRUD APIs, to enterprise-style mocking. Python ships with http.server, a simple web server module. It’s the fastest way to expose a directory of files over HTTP. python3 -m http.server …  ( 9 min )

What Is Sentence-Transformers (SBERT)? When I first explored text similarity, it was for an exam management system. The problem? Sometimes different teachers unknowingly entered the same question twice in the database just phrased a little differently. Traditional keyword-based matching struggled with this, since two questions could look different on the surface but actually mean the same thing. For example: “What is the capital city of France?” To a keyword search, those might look different. But to a student (and to us), they’re clearly duplicates. This is where Sentence-Transformers (SBERT) comes in. By converting questions into semantic embeddings, SBERT allows us to measure how close two sentences are in meaning, not just in wording. That makes it perfect for detecting duplicate que…  ( 11 min )

Artificial intelligence tools like ChatGPT are great at generating text, but they don’t always “know” everything. Their knowledge is limited to what they were trained on, and that training data stops at a certain date. So, what happens if you want your AI to answer questions about new research, company documents, or yesterday’s news? That’s where RAG (Retrieval-Augmented Generation) comes in. What is RAG? RAG stands for Retrieval-Augmented Generation. It’s a technique that makes large language models (LLMs) smarter by connecting them to an external knowledge source. In simple terms: Retrieval = finding relevant information from a database, documents, or the internet. Generation = using that information to create a human-like answer. Think of it like this: How RAG Works (Step by Step) User …  ( 7 min )

Hey guys! It's great to be back! After a short break, I'm thrilled to dive back into the world of React with a topic that's central to modern web development: the big shift from class components to functional ones. The evolution of React from class components to functional components isn't just a simple facelift or a change in syntax—it represents a profound shift in how we approach component design and manage complexity. It's an intentional move toward making React codebases more predictable, understandable, and reusable. Before the introduction of Hooks, the primary way to build stateful, complex components was through the class component model. While powerful, they introduced several pain points that often led to confusion and verbose code: Complex this Context: Class components rely he…  ( 8 min )

Introduction When people think about machine learning, their attention often gravitates toward sophisticated algorithms like random forests, neural networks, or support vector machines. However, in practice, success in machine learning is not just about choosing the right model; it is about choosing the right features to feed into those models. The data we use has just as much influence on performance as the algorithm itself. If the dataset is bloated with unnecessary, irrelevant, or noisy features, even the best algorithms may struggle to produce accurate predictions. On the other hand, if we carefully select the features that matter most, our models become more interpretable, faster, and better at generalizing to unseen data. This process of identifying and selecting relevant variables i…  ( 11 min )

Migrating a large-scale production application is never a small decision especially when the application in question is powering wallet operations, bill payments and crypto-to-fiat conversions. For context, the system I worked on had grown beyond 120,000 lines of JavaScript, much of it mission-critical and actively serving users with real money flowing through it every single day. The push to migrate wasn’t just my personal, although I’d long advocated for TypeScript internally. The tipping point came through a combination of colleague feedback, developer pain around ongoing maintenance, and the long-term risks of leaving such a large system in “pure JavaScript mode.” I should also note that this work was heavily inspired by Ben Howdle.

PHP JIT Compiler: How It Works and Why It Matters Introduction PHP has traditionally been an interpreted language, which means that every time you run your PHP code, the Zend Engine parses and executes it line by line. With the release of PHP 8.0, a new feature called JIT (Just-In-Time) Compiler was introduced. JIT can significantly speed up certain types of operations by compiling PHP code into machine-level instructions that the CPU can execute directly. In this blog, we’ll explore: What JIT is and how it works in PHP How PHP worked before JIT A practical example showing the performance difference with and without JIT When JIT is most effective JIT (Just-In-Time) Compilation is a technique used by modern programming languages to improve performance.

The Butterfly Effect That Started It All Three years ago, I never imagined that sharing my YouTube earnings on Medium would lead to building a SaaS platform. But that's exactly what happened when a young programmer named Timur slid into my DMs after reading about my faceless YouTube channels and print-on-demand success. That single DM would become the foundation of ToolsTube, our all-in-one YouTube SEO platform that's launching today on Product Hunt. The Developer's Dilemma Working with Timur opened my eyes to something fascinating about backend developers. They're absolute wizards at solving problems, but there's a catch. They tend to focus intensely on developer problems and want to solve them with code, only to discover that hundreds of other developers have already built similar soluti…  ( 8 min )

This article provides a side-by-side comparison of the most common query operators in Shodan vs the latest syntax in ZoomEye.

Have you ever found a bug while just playing around with an app? In software testing, you don’t always need to fully prepare scripts to test a simple case. That's the power of unplanned testing. This is where two valuable methods come in: ad-hoc testing and exploratory testing. While ad-hoc and exploratory testing might seem similar, they are not the same. This article will explain the key differences, helping you understand when to use each approach to find more bugs and deliver a better product. 1. What They Are Ad-Hoc Testing Ad-hoc testing is an unplanned, continuous way of testing. It's done without any written documents, test cases, or plans. The main goal is to find bugs quickly by randomly trying things out. This type of testing relies entirely on the tester's experience and creati…  ( 11 min )

We’ve all seen it: AI is hungry for data. The more you feed it, the smarter it gets. But with new privacy regulations, user awareness, and the real risks of data breaches, the old “collect everything into one big dataset” approach isn’t sustainable anymore—especially in industries like e-commerce, healthcare, and finance. Two approaches that keep coming up in developer circles are synthetic data and federated learning. Both aim to protect privacy without slowing down innovation. Let’s unpack what they mean, when to use them, and some trade-offs to keep in mind. Synthetic Data: Fake Data, Real Value Synthetic data is artificially generated data that mimics the statistical patterns of real datasets. Instead of using actual customer records, you generate a dataset that “looks” and “behaves”…  ( 7 min )

The SaaS Growth Journey Every SaaS journey starts with an MVP. It’s lean, scrappy, and built to test an idea quickly. But if that MVP takes off, the real challenge begins: how do you grow it into an enterprise-ready product that can handle thousands of users, complex workflows, and strict compliance requirements? Many teams assume that the best path is to start from scratch. After all, a custom build promises control and flexibility. But as products grow, scratch builds often collapse under the weight of scaling. That’s why more and more teams are turning to boilerplates — not just for faster MVPs, but for sustainable growth into enterprise-grade platforms. Scratch builds feel empowering at first.

Introduction In modern AI applications, data validation, serialization, and consistency play a crucial role. Pydantic, a Python library for data validation using Python type annotations, offers powerful tools that can be leveraged alongside AI systems to ensure reliability and scalability. AI workflows often deal with unstructured, noisy, or inconsistent data. Pydantic provides: Data validation: Ensures input data conforms to expected formats before being processed by AI models. Type enforcement: Minimizes runtime errors by enforcing strict data typing. Serialization: Facilitates seamless conversion between JSON, dictionaries, and objects for API integration. AI models expect structured input. Using Pydantic, developers can define schemas for model inputs, ensuring only valid and sanitized data reaches the inference pipeline. from pydantic import BaseModel class TextInput(BaseModel): text: str language: str = "en" This guarantees that every input to an NLP model contains a text field and a language specification. Training datasets can have missing values or inconsistent formats. Pydantic models help enforce schema constraints during preprocessing, ensuring cleaner and more reliable training data. Many AI systems expose APIs for inference or data collection. Pydantic can be used to validate requests and responses, reducing errors in API communication. With Pydantic, validated inputs and outputs can be logged in a consistent format. This structured logging aids in explainable AI (XAI) by making it easier to trace how inputs lead to outputs. Reliability: Prevents malformed data from breaking pipelines. Scalability: Standardized schemas make it easier to scale AI applications across teams. Transparency: Improves debugging and auditability of AI decisions. Pydantic bridges the gap between raw, messy real-world data and the structured requirements of AI systems. By combining strong data validation with modern AI pipelines, developers can build robust, explainable, and production-ready AI applications.  ( 7 min )

Every developer knows the pain of debugging: Endless logs Cryptic error messages Hours wasted on Stack Overflow I used to spend half my day chasing down bugs.

AI can translate them into plain English. 💡 Prompt Example: “Here’s my error log: [paste]. Explain the issue in simple terms and suggest likely causes.” Why: You understand the bug’s root cause in minutes, not hours. 2️⃣ Generating Fixes with Context Instead of patching blindly, I feed both the error and the relevant code snippet to AI. 💡 Prompt Example: “This function throws an error: [paste code].

In the grand narrative of software development, Object-Oriented Programming (OOP) is often cast as the protagonist of reusability. We're taught that through encapsulation, inheritance, and polymorphism, we can build modular, Lego-like systems that are easy to extend and maintain. And for many decades, this story has held true. The class, the object, the interface—these are the bedrock concepts upon which vast digital empires have been built. But this narrative, compelling as it is, is incomplete. It risks overshadowing other, equally powerful—and in some contexts, superior—paradigms for achieving the holy grail of software engineering: writing code once and using it everywhere. The idea that reusability is exclusively, or even primarily, the domain of OOP is a misconception. From the stark…  ( 21 min )

Don’t wait for a hard token error. *What to maintain README.md: purpose/scope, quick arch note, stack & versions, common commands, recent decisions. HANDOFF.md: current status, open issues + next steps, paths/artifacts, latest test results, data/IO schemas, exact env (venv/conda/poetry) and package versions. One-shot prompt to refresh both """ Please update two files based on our recent work and decisions. *Why this helps Mitigates “context drift” long before you hit limits.

1. Introduction Consensus is the backbone of fault-tolerant distributed systems, ensuring that nodes agree on a single outcome even in the face of crashes, delays, or network partitions. Without consensus, systems risk split-brain scenarios, inconsistent reads, and conflicting writes. Algorithms like Paxos, Raft, and Zab power consensus in real-world infrastructure such as ZooKeeper, etcd, Consul, Spanner, and CockroachDB. By doing so, they provide the foundation not only for strong consistency models like linearizability but also for the coordination primitives that keep large clusters safe and reliable. From a theoretical perspective, consensus algorithms have three properties: Agreement – The decision value is the same for all correct processes. Validity – The decided value was prop…  ( 8 min )

It’s often said that “there are only two hard things in computer science: cache invalidation and naming things.” While naming is a matter of human semantics, cache invalidation is about maintaining the balance between performance and correctness. Caching accelerates applications by storing frequently used data closer to the consumer. But stale or inconsistent data can create reliability issues. This is where cache invalidation comes into play — deciding when and how cached data should be updated or removed. Data freshness vs. performance trade-off Frequent invalidation = fresh data, but lower performance. Rare invalidation = better performance, but stale data. Distributed systems complexity Multiple servers or nodes may have their own cache layers. Coordinating updates is non-trivial. Vari…  ( 7 min )

In the age of personal AI, robust technical architecture for privacy is only half the battle. The other half is governance: the system of policies, compliance measures, and trust frameworks that make an AI's privacy promises verifiable and accountable to the outside world. What it is: Policy Binding means that every piece of user data is encapsulated in a protected object that contains not only the encrypted content but also a machine-readable policy. This policy dictates who can access the data, for what purpose, and for how long. How it Works: As data moves through the AI system, "privacy guardrails" at every step check these embedded policies before allowing any action. For example, if a piece of data is tagged with a policy stating "Do not use for marketing," any attempt by an analytic…  ( 8 min )

In the new era of personal AI, safeguarding user privacy isn't just a legal checkbox—it's an engineering cornerstone. Recent data breaches at major AI providers have sent a clear message: to earn user trust, personal AI systems must be built from the ground up with robust privacy protections. Data Minimization: The system should only collect data that is adequate, relevant, and necessary for the user's purpose. Instead of hoarding data, start with the question: "How little information do we need to deliver a great experience?" End-to-End Encryption: All data must be encrypted in transit (using HTTPS/TLS) and at rest (using standards like AES-256). Crucially, the architecture must ensure that not even internal employees can access unencrypted user data. Pseudonymization by Default: In your …  ( 8 min )

ETL, the abbreviation of extract, transform and load, is the process of moving data from one or more sources to a target system through extraction, transformation and loading. A regular ETL process should stick to the order of extracting data, transforming data and then loading data into the target system (usually a database). The data finally loaded into the database should be the desired result. However, this reasonable order is often changed in the actual execution of the process. ETL becomes ELT or LET, where the source data is loaded to the target database before it is transformed or even extracted. The source data may come from different sources, such as database, file and web, and has different levels of data quality. Both E and T are computation-intensive, and among a variety of da…  ( 11 min )

First() and FirstOrDefault() in C#: A Beginner's Guide Tired of writing clunky loops to extract the first element from a collection in C#? Wish there was a simpler, more elegant way? Well, you're in luck! C# provides two incredibly useful methods, First() and FirstOrDefault(), designed precisely for this purpose. This tutorial will guide you through their functionality, differences, and practical applications. First() The First() method, as its name suggests, retrieves the very first element from a collection (like a list, array, or query result). It's straightforward and efficient. However, there's a catch: if the collection is empty, First() throws an InvalidOperationException. This can be problematic if you're not sure whether your collection will always contain elements.

When you search on Google, the result you see is made up of a few important parts. As a site owner or developer, you can influence how your page appears, but Google ultimately decides what to display. Understanding this helps you write better titles and descriptions that attract clicks. The most visible part of a search result is the blue clickable title. Google usually takes this from your HTML tag, but it does not always follow your exact wording. If your title is too long, Google will cut it off with three dots at the end. A good rule is to keep your title around 50 to 60 characters. That way, it has a higher chance of showing in full. For example: Too long: “Learn How to Build an End to End Web Application with React, Node.js, MongoDB, and Tailwind CSS” Better: “Build a Web App…  ( 7 min )

For years, the value of artificial intelligence has been calculated on a simple premise: productivity. We have measured AI's success in hours saved, tasks automated, and output maximized. This "Productivity AI" paradigm has given us powerful tools, but it has also trapped us in a narrow view of what AI can and should be. They are narrow: Not everything of value can be measured in units of output. A focus on efficiency overlooks the deeper ways AI can enhance our lives, from fostering creativity to improving mental health. They are elusive: Even on their own terms, the productivity gains from AI can be difficult to measure accurately. The true ROI is often subtle, long-term, and intertwined with complex human factors. The limitations of this old model are pushing innovators to ask a differe…  ( 8 min )

When you style web pages with CSS, every element on the page is treated as a box. This is known as the CSS Box Model—a fundamental concept that determines how elements are sized, spaced, and interact with each other. Whether you’re aligning text, building layouts, or troubleshooting spacing issues, understanding the box model is essential. In this post, we’ll break down the components of the CSS box model: content, padding, border, and margin. Every HTML element is essentially a rectangular box. The box model helps the browser calculate: The total space an element occupies How elements are positioned relative to each other The visible boundaries of content Content → The innermost area where text, images, or other content lives. Padding → The space between the content and the border. Border…  ( 8 min )

Kenya has proudly worn the crown of the “Silicon Savannah” for over a decade, fueled by innovations like M-Pesa and a vibrant startup scene. But as we enter a new era, one driven by Big Data, Web3, and AI, it is worth asking: are we truly ready to lead the next wave of global technological transformation? Kenya’s data powers global AI, but who owns the results? Are we shaping the future, or just supplying the raw material while others cash in? If we don’t invest in local talent, sovereign data repositories, and home-grown AI, we’ll stay data laborers in someone else’s revolution. It’s time to decide: do we build, or just get mined? Web3 promises decentralization and inclusion, but in Kenya, it’s mostly about crypto trading. Where are the startups using blockchain to fix land fraud, or smar…  ( 7 min )

If your decentralized social platform permanently records every like, comment, and connection on a public ledger, you haven't disrupted Big Tech surveillance, you've made it immutable. Web3 social media promised to fix everything wrong with centralized platforms: no more shadow banning, algorithmic manipulation, or corporate data harvesting. The vision was compelling, users own their data, creators get fair compensation, and censorship becomes impossible. But as these platforms launch in 2025, a fatal flaw is becoming clear: transparent blockchains create worse privacy problems than the platforms they're trying to replace. When every social interaction becomes a permanent public record, we haven't liberated social media, we've built the ultimate surveillance state. Traditional social medi…  ( 8 min )

(And How to Fix It) If your tokenized real estate broadcasts the property address, sale price, and buyer identity to everyone on Earth, you haven't revolutionized finance, you've created a stalker's paradise. Real-world asset (RWA) tokenization has exploded to over $30 billion by September 2025, promising to unlock trillions in previously illiquid assets. Property deeds, art collections, intellectual property, even rare wines, everything's getting tokenized. But there's a massive problem most platforms ignore: complete transparency is killing institutional adoption. When every transaction detail lives permanently on public blockchains, we're not democratizing finance, we're creating a surveillance economy.

Introduction Transport Layer Security (TLS) is the backbone of any modern web service. As an SRE, you know that a mis‑configured TLS layer can expose sensitive data, degrade performance, and even break compliance audits. This guide walks you through the seven most common pitfalls when hardening Nginx for TLS in a production environment, and shows you how to fix them with concrete configuration snippets. Nginx ships with a generic set of ciphers that prioritize compatibility over security. This often leaves you vulnerable to attacks like Logjam or BEAST. What to do: Prefer modern, AEAD ciphers (AES‑GCM, ChaCha20‑Poly1305). Disable weak algorithms such as RC4, DES, 3DES, and MD5. # /etc/nginx/conf.d/ssl.conf ssl_protocols TLSv1.2 TLSv1.3; ssl_ciphers \ 'TLS_AES_256_GCM_SHA384:TLS_C…  ( 8 min )

Introduction Sometimes we need to keep data secret—like passwords, personal details, or private messages. AES (Advanced Encryption Standard) is a very popular way to do this. AES is a method of turning normal text into unreadable text (encryption) and then back to normal (decryption) using the same secret key (symmetric algorithm). When you need to protect sensitive information—such as passwords, financial data, or confidential messages—encryption is essential. Before you start: Install Python 3.7 or newer. Install the Python package cryptography by running: pip install cryptography AES is a symmetric key algorithm, which means the same secret key is used for both encryption and decryption. Key sizes supported by AES: 128 bits 192 bits 256 bits (the strongest and what we use in this exa…  ( 7 min )

This content was created for the purposes of entering the GKE Turns 10 Hackathon Traditional credit card applications are painfully slow, opaque, and often miss the mark on what customers actually need.

Originally published on my learning journey blog Alright DEV community, time for some brutal honesty: I spent two entire years actively avoiding Kubernetes like it was my ex at a coffee shop. My sophisticated deployment strategy? SSH into a DigitalOcean droplet, git pull, and pray nothing breaks. Elegant, right? But here's the kicker - I wasn't just avoiding K8s because I was lazy. I was genuinely terrified of it. And according to some recent research I dug into, I wasn't alone in this fear. Let me paint you a picture of my pre-K8s life: Step 1: SSH into production server Step 2: sudo systemctl stop my-app Step 3: git pull origin main Step 4: npm install (and hold my breath) Step 5: sudo systemctl start my-app Step 6: Check if site still works Step 7: Panic if it doesn't Sound fami…  ( 8 min )

I explained System Design to my friend using a pizza shop 🍕 1️ Scalability – More chefs, more pizzas @RestController class PizzaController { @GetMapping("/order") String orderPizza() { return "🍕 Pizza ready!"; } } 1 instance = 10 orders/min @GetMapping("/order") String orderPizza() throws InterruptedException { Thread.sleep(3000); // 3 sec delay return "🍕 Pizza ready after wait!"; } Delays = unhappy customers Run a load test: ab -n 1000 -c 50 http://localhost:8080/order One endpoint, but throughput depends on kitchen “power.” 4️ Consistency – Pizza means pizza @RestController class PizzaController { @GetMapping("/order") String orderPizza() { return Math.random() > 0.7 ? "🍝 Pasta?" : "🍕 Pizza"; } } Users want the same result every time! @GetMapping("/health") String health() { return "✅ I’m alive!"; } Service stays open, even if one instance crashes. System design is like running a pizza shop 🍕 Scalability → more chefs Latency → wait time Throughput → orders per min Consistency → pizza = pizza Availability → always open What’s your favorite system design analogy?  ( 6 min )

🚀 Install and Use FSCSS (v1.1.7) FSCSS (Figured Shorthand Cascading Style Sheets) introduces shorthand features that make writing CSS faster, smarter, and more dynamic. You can use FSCSS via CDN for quick tests or compile to CSS for large production projects. Install via NPM (Recommended for projects): npm install -g fscss This installs FSCSS globally so you can use the fscss command anywhere. For large-scale or production projects, you should compile FSCSS into CSS before deploying. Example: fscss style.fscss style.css style.fscss → your shorthand stylesheet style.css → the compiled standard CSS output. Example linked the style.css to html: 👉 This ensures faster load times, better performance, and no runtime overhead. If you just want to experiment or add dynamic runtime styles, you can load FSCSS from CDN: This way, FSCSS runs directly in the browser — but it’s not recommended for big projects. FSCSS runtime is required whenever you use features that need randomization or loops at runtime: / Example: Randomized display / .post { display: @random([block, none]); } When compiled, @random() resolves to a fixed value. With runtime, it randomizes every page load without extra JavaScript. Use Case Recommended Method Why Quick tests, demos, small apps CDN runtime No setup required, works instantly Large/production projects CLI compile Faster load, optimized CSS, no runtime overhead Dynamic styles (random, loops) CDN runtime Needed for non-deterministic behavior ✅ Use CLI compile (fscss style.fscss style.css) for production ✅ Use CDN runtime only when dynamic/non-deterministic styles are required ✅ Always compile + minify CSS before deploying ✅ Avoid inline // comments (use / ... /) ✅ Keep FSCSS files modular and organized 👉 Try the online compiler: Upload FSCSS & Compiler  ( 7 min )

When it comes to product development, many teams—whether product managers, engineers, or even stakeholders—tend to get caught up in the excitement of new features. A feature may sound fantastic on paper, or research may suggest it could be a game-changer. Teams often rally behind these ideas with great enthusiasm. But here’s the critical question: 👉 Is that exciting feature really worth prioritizing over everything else? This is where many organizations stumble. Bugs pile up, timelines stretch thin, and the “next big thing” in the backlog steals attention from what truly matters. In large corporations with deep pockets, chasing the wrong features might not be fatal. But in the startup world, burning cash on low-impact features is one of the fastest ways to fail. So, how do effective leade…  ( 7 min )

How a simple unique value prevents duplicate payments, double orders, and customer frustration. You’re finalizing a purchase online. You click "Pay Now." The page hangs. The spinning wheel mocks you. Did it work? You have no idea. Your natural reaction is to hit the refresh button or click "Submit" again. But what happens next? Does the merchant charge your credit card twice? In the world of distributed systems and unreliable networks, this scenario isn't just a nuisance it's a fundamental challenge. How can you ensure that a single, errant API request doesn't accidentally create two orders, process two payments, or activate two devices?

Introduction Dataset Overview Replaced blanks in the review and ratings columns with 0 for completeness. Converted the prices columns to numeric format Discounts converted from string to numerical values. Ratings extracted from text format to numeric format (e.g. 4.5 out of 5 to 4.5) Reviews standardized to numeric values. Removed duplicates. Data Enrichment Added new columns to categorize products based on their ratings("Poor" for ratings below 3, "Average" for 3-4, and "Excellent" for 4.5 and above). Created a new column to categorized products based on discount percentage ("Low Discount" for 40%). Calculated the absolute discount amount for each product (Old Price - Current Price). Figure below shows the enriched data Key Insights Average price: Ksh 1,181 Average discount: approximately 36.8% Highest discount: 64% Lowest discount: 1% Total reviews analyzed: 723 Average product rating: approximately 2 Discount Analysis Ratings and Reviews Analysis Products Conclusion In conclusion this report analysis shows us that discounting alone is not driving sustainable sales growth or customers loyalty. The analysis shows that while Jumia is offering a significant discounts the overall customer experience remains poor, the ratings and reviews are poor. Jumia needs to take different actions to ensure that there business is growing. Jumia should incentivize reviews by offering voucher rewards, loyalty points, or discount coupons for verified feedback. Jumia must shift from price-driven competition to a value-driven strategy. By elevating product quality, spotlighting high-rated categories, optimizing discount ranges, and building trust through reviews, Jumia can boost conversions, reduce returns, and grow long-term customer loyalty.  ( 7 min )

The Single-Box Tax: Why My Friend Was Sketching Shards at Olive Garden True story: I’m at dinner with a friend. Halfway through his pasta, he tells me about a “simple” weekend project where he'd make search feel smarter. Keep Postgres because he knows it well, add pgvector for embeddings, ship by Monday. Clean plan. Familiar tools. It works… for about two days. By Wednesday the loading spinner is basically the main character. Support screenshots all look the same. He tweaks settings, rents a bigger box, pushes a few jobs to a side worker. Things calm down, then spike again. At some point he pulls out a pen and starts sketching a sharding plan on the Olive Garden napkin. We laugh, because nobody wants to do shard math between breadsticks. Here’s the important part: his plan wasn’t wrong. …  ( 8 min )

From 10-Week Project to Long-Term Partnership Samina Rahman Purba ・ Sep 22 #startup #programming #showdev  ( 5 min )

Thank you, from the bottom of my heart 💌 Huge thanks to everyone who read my last post, From Dev.to Posts to Running a Startup, and gave me a follow here on DEV. I never expected that sharing my entrepreneurial journey — the ups, downs, and struggles — would resonate with so many people. In my previous post, I briefly mentioned the early days of my studio Foam On Latte and how difficult it was to land clients consistently and get them to pay us what we deserved. After months of underpricing ourselves and battling constant self-doubt, fear of failure, and rejection, we finally found some stability. So, I'm going to make it a habit to post weekly about what I'm learning and building in my digital product studio. In these weekly blogs, I'll document product building, forming partnerships, …  ( 8 min )

Expectation Roulette One endpoint expected: active=true Another wanted: is_active=1 And a third, authored long ago by an ancient intern whose spirit still haunts the codebase, insisted on: activeness=Activeness.YES All technically correct. It’s like discovering every traffic light in your city has its own personal theory of “green.” And the buttons - dear god, the buttons. felt it. The intent was noble, or at least convenient. “This endpoint just needs to ship.” “That button style was faster to copy-paste.” “We’ll circle back later.” Every inconsistency was a tiny act of local optimization. Freedom for the team, speed for the sprint, autonomy in the moment. Nobody thought they were authoring scripture. Soon, the system resembled a modern art gallery: a thousand pieces, each with its own interpretive plaque. Docs multiplied and lack pings became ritual: “Which version of ‘active’ is correct here?” It wasn’t documentation anymore. Call it Predictability Drift, Death by Exceptions, or my personal favorite: Chaos Tax. Every deviation added overhead. Inconsistency doesn’t scale linearly - it compounds. Here’s the lens that finally clicked for me: predictability is velocity. Consistency isn’t ascetic minimalism or bureaucratic purity. Predictable systems don’t demand attention. These days, I’m less impressed by clever abstractions and more impressed by boring consistency. Because nothing feels faster than a system that doesn’t make you ask twice. So yes, give me one predictable flag. active=true. is_active=1. activeness=Activeness.YES (may the ancient intern rest in peace). Just one truth, boring enough to believe in. One filter to rule them all.  ( 7 min )

Merkle trees are one of those concepts that quietly power some of the most important technologies we use today—Git, blockchains, and peer-to-peer systems like IPFS. They provide a compact way to prove that a piece of data belongs to a larger dataset, without needing to reveal or send everything. But Merkle trees are often introduced only in the context of massive distributed systems. What if you just want to play with them locally, on your laptop, using tools you already know? That's where SQLite comes in. In this tutorial, we'll build a Merkle tree in Python and persist it to SQLite. By the end, you'll have a working project that can: Build a Merkle tree from arbitrary strings. Store all nodes—leaves and internal hashes—in a relational database. Query inclusion proofs for any leaf. Verify…  ( 11 min )

*The Problem That Kept Me Up at Night You know that feeling when you're about to deploy to production? That pit in your stomach wondering "what if this breaks everything?" So I Built FlagSwift What it does: ✅ Simple dashboard to create and manage feature flags What it doesn't do: ❌ Require a PhD to set up Quick Example import { FlagProvider, useFlag } from '@flagswift/react-client'; function App() { return ( ); } function MyComponent() { const isNewFeatureEnabled = useFlag('new-checkout-flow'); return ( : } ); }` Try It Out Application: FlagSwift npm install @flagswift/react-client It's free while in beta What I'm Looking For: Honest feedback from real developers: Would you actually use this? (Please be brutal - I can handle it) Why I'm Sharing This? Because I think every developer deserves to deploy without fear. And if this helps even one person sleep better after hitting deploy, it's worth it. Also, I genuinely want to build something people actually want to use, not just something I think is cool.

As developers, we spend our days thinking about systems, rates, and consumption (like API calls or memory usage). Your electricity bill is just another system with its own set of variables and logic. Let's break it down. Joule: Think of this as a single unit of work, the base integer. It's too small to be practical for billing. Watt: This is a rate. It's not a quantity; it's Joules/second. In programming terms, it’s not the total data, but the throughput (e.g., MB/s). An appliance's Wattage is its fixed consumption rate. BTU: A domain-specific unit for thermal energy. It's like a library you'd only use for a specific task (heating/cooling). 1 Watt ≈ 3.41 BTU/hr. You're not billed for the rate (Watts), you're billed for the total consumption over time. This is the kilowatt-hour (kWh). The function is simple: function calculateKwh(wattage, hours) { // A kilowatt is 1000 watts const kilowatt = wattage / 1000; const kwh = kilowatt * hours; return kwh; }``` If your electric rate is $0.15/kWh, the cost function is just calculateKwh(wattage, hours) * 0.15. Why This Matters Understanding this logic allows you to identify the most "expensive" functions in your home's "runtime." It's not always the device with the highest wattage, but the one with the highest wattage that runs for the longest time. I wrote a more detailed, plain-language guide on this that breaks down the concepts for everyone. You can check it out here, and the site itself has some useful unit conversion tools.

Workflow automation is a big deal these days and n8n has quickly become a favorite among DevOps engineers and developers for building powerful automations with a visual interface. But what happens when your environment is air-gapped (no internet access)? In this guide, I’ll walk you through the step by step process of installing and configuring n8n on an air-gapped RHEL server. Why Air-Gapped? Air-gapped systems are isolated from external networks for security reasons. This is common in finance, defense, healthcare, and enterprise environments. While it provides strong security, it also makes setting up applications like n8n tricky since you can’t just docker pull or npm install. Prerequisites RHEL 8.x or 9.x installed Root (sudo) access to the server A workstation with internet access to …  ( 8 min )

A well-written function is like a craftsman's tool—perfectly suited to its task, reliable in your hands, and beautiful in its simplicity. It does exactly what its name promises, nothing more, nothing less. The best functions announce their purpose clearly: def calculate_circle_area(radius): return 3.14159 * radius * radius def is_valid_email(email): return '@' in email and '.' in email.split('@')[1] def format_currency(amount): return f"${amount:.2f}" Each name tells you exactly what happens inside. No mystery, no surprises. When you see calculate_circle_area(5) in your code, you immediately know what's being calculated and what you'll get back. Great functions do one thing completely: def read_file_lines(filename): with open(filename, 'r') as file: return file.r…  ( 8 min )

When I was in-between jobs, I wanted to do a fun project and improve my German, so I built a little web app called Wörtilizer 🇩🇪⚡ Wörtilizer lets you build up your own private German vocabulary, automatically get the correct der-die-das noun articles, and memorize them via visual cues and a fun quiz. The web app was built via React, Next.js, and Tailwind CSS. It uses the german-words and german-words-dict npm packages to discover whether the word is in German, it is indeed a noun, and what is its article. The data is saved in your browser's localStorage, no signup/login needed. I made it responsive, so it should look nice on any device. There are some limitations, like the dictionary recognizes most words but not all of them. Also, the words that it does recognize need to be accurately spelled, but that's not a bug, it's a German learning feature 😉 Try out Wörtilizer on your next U-Bahn ride instead of doom scrollen. Wörtilizer is open sourced on GitHub, so feel free to steal it or contribute.  ( 6 min )

Single Page Applications (SPAs) power most modern web apps—React, Vue, Angular, Svelte—you name it. They deliver seamless experiences, lightning-fast navigation, and an “app-like” feel. But here’s the catch: while SPAs thrill users, they frustrate search engines. SEO is still where SPAs stumble hard in 2025. At the core, SPAs shift rendering to the browser. That means: Crawlers often see empty HTML shells. Heavy JS bundles delay when content becomes visible to indexers. Client-side routing can leave important pages undiscoverable. Social previews break when OG/Twitter meta tags aren’t injected server-side. So the site looks perfect for humans… but not for search engines.

Unlocking Explainability Transparency with SHAP Values: A Code Snippet for AI Governance In the pursuit of building trustworthy AI systems, explainability and transparency have become essential components of AI governance. One key technique for achieving these goals is the use of SHAP (SHapley Additive exPlanations) values. SHAP values provide a way to assign importance scores to individual input features, helping to illuminate the decision-making process of complex AI models. Code Snippet: SHAP-Enabled Explainability Below is a Python code snippet that demonstrates how to leverage SHAP values to generate feature importance for an AI model. python import shap from sklearn.model_selection import train_test_split from sklearn.ensemble import RandomForestClassifier from sklearn.datasets import load_iris class AIModel: def __init__(self, model): self.model = model def explain(self, input_data): # Use SHAP values to generate feature importance ... --- *This post was originally shared as an AI/ML insight.

I had someone ask me to restore an item from the recycle bin in XM Cloud today. Generally not a difficult task, assuming it hasn't been 30 days since the deletion when it should get flushed. But, I've come to find that the recycle bin in XM Cloud, while it has a search, that search...doesn't work. You get a script error. Now, in the collection of tools, the recycle bin seems to be a relic of the "old" era - it's in the Desktop of the Content Editor system, and I don't as yet see an equivalent in Explorer or Pages. But it's still a pretty useful tool. Fortunately, there's another way to do this...good old Sitecore PowerShell. I remembered from something else I was messing with once that there was a way to get into the recycle bin, so a little documentation and AI searching and crafting, and we get the following number. This script will both search for a term in the name or original path, and if you choose will restore the item(s) back to the master database. A quick little workaround for that pesky search problem! $searchTerm = "" $restoreItems = $false $database = Get-Database -Name "master" $archive = Get-Archive -Database $database -Name "recyclebin" # Get all items in the recycle bin $archiveItems = Get-ArchiveItem -Archive $archive | Where-Object { $_.Name -match $searchTerm -or $_.OriginalLocation -match $searchTerm } foreach ($archivedItem in $archiveItems) { Write-Host "Found deleted item: $($archivedItem.Name) | ID: $($archivedItem.ArchivalId) | Path: $($archivedItem.OriginalLocation)" if ($restoreItems) { Restore-ArchiveItem -Archive $archive -ItemId $archivedItem.ArchivalId Write-Host "Restored deleted item: $($archivedItem.Name) | ID: $($archivedItem.ArchivalId) | Path: $($archivedItem.OriginalLocation)" } }  ( 6 min )

The AI Governance Conundrum: Fairness in Autonomous Healthcare Decision-Making In the realm of autonomous healthcare systems, AI algorithms are increasingly being used to make life-critical decisions, such as allocating limited organ transplants. However, these systems often face the daunting challenge of balancing competing priorities, including high-value social utility and individual prognosis scores. To address this conundrum, we need to design a fairness mechanism that ensures equitable allocation of resources while minimizing disparities. The Complexities of Fairness Fairness in AI decision-making involves multiple dimensions, including: Individual fairness: Treating similar patients similarly, regardless of their background or demographics. Group fairness: Ensuring that certain groups are not systematically disadvantaged or favored in the allocation process. Distributive fairness: Allocating resources in a way that benefits the greatest number... This post was originally shared as an AI/ML insight.

As distributed training continues to evolve, I predict we'll see a significant shift towards task-based, hybrid training paradigms that combine on-device learning with cloud-based data aggregation. This fusion of on-premise and cloud computing will unlock unprecedented scalability, efficiency, and model performance, revolutionizing the way we train and deploy AI models. Task-Based Training Task-based training involves dividing complex tasks into smaller, manageable components that can be executed on various devices, from mobile phones to high-performance computing clusters. This approach enables more efficient use of resources, reduces training times, and improves model generalizability. Hybrid Training Paradigms Hybrid training paradigms combine the strengths of on-device learning and cloud-based data aggregation.

Over the years of working with software delivery teams, I have seen projects succeed when their foundation was solid and stumble when it was not. That foundation in app development often comes down to how you structure your codebase and coding standards. A blueprint is not just a project template. It is a collection of coding standards and patterns applied consistently across your project. The goal is simple: reduce repetitive decisions, enforce best practices, and allow developers to focus on business logic rather than boilerplate. In practice, setting up and enforcing these blueprints takes time. Tools like HuTouch have packaged them further extending the Automation vs Prompts narrative OR solve for repetitive tasks 1st to build WORK2.0, but before we get there, let us understand why eac…  ( 9 min )

Every few months, a new wave of concern sweeps through schools: students are “cheating” with AI. Detection tools pop up, policies tighten, and essays are scrutinized. But maybe we’re asking the wrong question. Instead of worrying about how to stop AI, should we be asking how to use it to help students learn? Our traditional homework model (write an essay, turn it in, get a grade) doesn’t make much sense in an AI era. Arguably, it never really did. Schools often seem designed to measure performance rather than nurture learning. What is the real goal of schools? Is it knowledge? Or preparation for life and work? Either way, assignments should reflect that goal, and for years they haven’t. Part of education should be learning to use the tools we already have at our disposal, such as search en…  ( 7 min )

I had to partially take a step back from my original idea, because I wanted to integrate a CSS framework in my web components, but the two I was choosing between don’t fit. That’s why I chose to use only “vanilla” styles and JavaScript instead. Anyway, let me talk about them. I’m a huge fan of Bootstrap: it’s, maybe, the first framework I’ve ever approached as a front-end developer, and I still use it when I can. I’ve never learned Tailwind CSS at 100%, and I joined the waitlist for a course already. So, trust me if I say that I’ve nothing against them. Unfortunately, however, neither of them works well with web components: we have at least two problems here, starting from the shadow DOM.

Introduction AI is rapidly evolving and disrupting many industries. Initially, LLM agents were only able to provide us insights based on their training data, which was very limited and this prevented us from using AI agent from obtaining real-time insights and using it efficiently in an enterprise context. The introduction of MCP (Model Context Protocol) became a game changer in this field and it enabled the AI agents to get the real-time information and also to access enterprise data, which unlocked a whole new scope for using AI agents and implementing powerful new use-cases. In this post, I would like to share my learning about MCP Server and also a walk through a sample project where I am getting the factory machine data stored in a PostgreSQL database using MCP Server and the AI a…  ( 8 min )

I’ve got to get this off my chest: every DevOps article out there makes it sound like you need AWS, GCP, or some other bloated cloud provider just to spin up a container. Bullshit. You don’t. Not if you’re running a local machine with half a brain and an old server lying around. I’ve been playing around with Docker locally for a while, and honestly? It’s faster, cheaper, and sometimes more fun than the cloud. Here’s why, and how you can do it without losing your mind. Why the hell would you do this? First off, speed. Launching a container locally takes seconds, not minutes while some cloud console spins up instances somewhere in the middle of nowhere. No network lag, no random API failures, no surprise bills at the end of the month. Second, cost. If you already have a spare server (or even…  ( 9 min )

Ever wondered how Docker can launch a new container from a multi-gigabyte image in just a fraction of a second? If you were to copy all that data, it would take ages. The magic behind this speed and efficiency is a clever strategy known as Copy-on-Write (COW). It's one of the foundational concepts that makes Docker so powerful. Let's break down what it is and how it works. At its core, Copy-on-Write is a resource-management technique. The name says it all: you delay or defer the copying of data until the very first time you need to write or modify it. Think of it like working with a master template in a team. Imagine a master document (the template). Instead of everyone making their own full copy to work on, they all view the same master template. When someone needs to make a change, they …  ( 8 min )

A critical infrastructure protection program is essential for safeguarding vital systems that modern society depends on. These systems include electrical grids, telecommunications networks, water treatment facilities, and transportation infrastructure.

Hey folks! We've gotten some feedback about issues related to the Nuclia trials for the Dev Challenge. First off, I want to apologize – we thought we had adjustments to the trial process cleared and ready in advance of the hackathon, but turns out...not so much. 🙃 Totally a mistake on our end, and we're sorry for the inconvenience and confusion. That being said, we do have some workarounds ready so you can still participate in the "RAGs to Riches" category! Some folks have mentioned being unable to start a Nuclia free trial without a corporate email. To fix this, please reach out to me at nanz @ progress.com (or on the Progress Labs Discord) with the email you'd like to use, and I'll manually override the block and start your trial account with whatever email you'd prefer. There's been some concern about the 14-day free trial timing out before the judging period. There are two ways to solve this: either reach out to me (over email or Discord, as above) and I can manually extend your trial OR just take a short video of your app and include it in the submission template. Thanks so much, and again – very sorry for any trouble! We're super excited to see what you build, and here to help support however you need.  ( 6 min )

Docker Architecture ? The above picture, clearly indicates that Docker Deamon is brain of Docker. If Docker Deamon is killed, stops working for some reasons, Docker is brain dead :p (sarcasm intended). We can use the above Image as reference to understand the lifecycle of Docker. There are three important things, docker build -> builds docker images from Dockerfile docker run -> runs container from docker images docker push -> push the container image to public/private regestries to share the docker images. The Docker daemon (dockerd) listens for Docker API requests and manages Docker objects such as images, containers, networks, and volumes. A daemon can also communicate with other daemons to manage Docker services. The Docker client (docker) is the primary way that many Docker use…  ( 8 min )

I rewrote and published a library for image zooming like in Medium. It’s Framework agnostic, small, dependencies free, and now (more or less) modern. The original library seemed to be abandoned for a few years now, and I needed some changes in it for my portfolio website, so I took it in my own hands. The changes include, but are not limited to, adding a new method to swap zoomed images, updating event handlers to allow pinch-to-zoom on touch screens, rewriting to TypeScript, and modernizing the setup by changing most of the libraries and workflows. https://github.com/SpasiboKojima/medium-zoom-next I’ll be glad for any feedback! A full changelog with some explanations is here: https://github.com/SpasiboKojima/medium-zoom-next/pull/2  ( 6 min )

Here’s a truth bomb from many years in the tech world: we overcomplicate things. We get seduced by features we don’t need, especially when it comes to hardware. The question "What is monochrome printing?" often gets a textbook answer: "printing in one colour, typically black." And while that's technically correct, it's a useless answer if you're trying to decide how to equip your office or home workspace. The real answer isn't about colour; it's about context, efficiency, and removing pointless complexity. Let's talk about what monochrome printing is in the real world: a strategic tool for clarity and reliability. It's Not a Limitation, It's a Specialization The biggest misconception is that monochrome printing is a lesser version of colour printing. This is like saying a dedicated datab…  ( 8 min )

The Modulax Airdrop System is not just another token giveaway. It is a structured mechanism designed to reward consistent participation, onboard early supporters, and bridge ERC-20 holders into the native Modulax economy. Modulax uses daily native $MDX rewards for ERC-20 holders, rather than one-time snapshot farming. This means rewards are tied to holding behavior over time instead of short-term speculation. Holders must maintain a minimum balance of 0.5% of the ERC-20 supply. Rewards scale with percentage held. Distributions are made daily in native MDX on Modulax mainnet. Reward Schedule ERC-20 Holding (%) Daily Native Airdrop (MDX) 0.5% 1,000 MDX 1.0% 2,000 MDX 2.0% 4,000 MDX Snapshots of ERC-20 balances are taken daily Rewards are calculated based on the percentage of s…  ( 7 min )

Introduction Before delivering a solution to end users, ensuring its security is critical. Two common practices, especially in Hong Kong, are: Security Risk Assessment and Audit (SRAA): Evaluates the security risks inherent in the system. Privacy Impact Assessment (PIA): Ensures the system complies with privacy regulations and safeguards sensitive data. While these assessments are crucial, they often require external audits or third-party tools. To smoothen the process and identify vulnerabilities early, developers can step into the realm of penetration testing (pen-testing). Penetration testing is a proactive approach where developers simulate real-world attacks on their applications. This helps uncover vulnerabilities like injection flaws, weak authentication, and insecure configu…  ( 10 min )

Introduction Financial data rarely moves in a straight line. Instead, it often swings between periods of calm and turbulence. Traditional tools like regression or basic time series models are helpful for identifying long-term trends, but they fall short when it comes to measuring volatility—the unpredictable ups and downs that dominate markets, currencies, and even emerging businesses. To deal with this challenge, econometricians introduced models such as ARCH (Autoregressive Conditional Heteroskedasticity) and its more advanced counterpart, GARCH (Generalized ARCH). These models don’t just look at the central trend of a dataset; instead, they focus on the variance of errors over time, making them especially powerful for analyzing financial markets. From ARCH to GARCH When researchers firs…  ( 9 min )

Let’s cut the corporate jargon. I’ve been in the SEO trenches for 15 years. I’ve seen algorithms rise and fall, from Panda to Penguin to the AI-powered beast that is Google today. And throughout this entire time, the single biggest mistake I see businesses make is treating "computer and mobile" as a technical checklist. You’ve heard it all before: "Mobile-first indexing!" "Responsive design!" "Core Web Vitals!" So, you hustle. You make your site fast. You make it responsive. You tick all the boxes. And then… crickets. Your traffic is mediocre, your engagement is low, and your conversions are non-existent. Why? Because you’re optimizing for devices, not for people. And after 15 years, I can tell you with absolute certainty: Google’s ultimate goal is to understand people. If you want to win,…  ( 8 min )

Many teams struggle with duplicated response wrappers in their generated API clients. Every endpoint ends up with its own ServiceResponseFooResponse, ServiceResponseBarResponse, … all repeating the same fields. Boilerplate everywhere. In this post I’ll show a clean approach to generating type-safe generic clients with Spring Boot 3.4 + OpenAPI Generator 7.x — powered by a tiny Mustache customization. ✅ No duplicated wrappers Problem Default OpenAPI Generator doesn’t handle generics. It produces one “wrapper” model per endpoint, duplicating fields like status, message, and errors across dozens of classes. This is noisy and hard to maintain. Solution We introduce a single generic base class: public class ServiceClientResponse { private Integer status; private String message; private List errors; private T data; } …and let generated wrappers simply extend it: public class ServiceResponseCustomerCreateResponse extends ServiceClientResponse {} That’s it: no duplicated boilerplate, while keeping typed getData() access. How? OpenApiCustomizer marks wrapper schemas in the spec. Tiny Mustache partial (api_wrapper.mustache) tells the generator to render thin shells instead of full models. The result: clean, DRY clients that still feel natural to use. Demo Repo spring-boot-openapi-generics-clients Deep Dive Article 👉 Type-Safe Generic API Responses with Spring Boot 3.4, OpenAPI Generator, and Custom Templates 💡 This pattern scales well across microservices and saves teams from maintaining dozens of duplicated wrapper classes. If your APIs already use a common response envelope, this approach will simplify your client layer dramatically.  ( 6 min )

TypeScript Generics A Practical Guide to Reusable Code As a developer, you've probably faced this problem: you write a perfectly good function that works with numbers, but then you need the exact same logic for strings. Or arrays. So what do you do? You could copy and paste the function and change the types, but that leads to duplicate code. Or you could use the any type, but that throws away all the type safety that makes TypeScript great. There’s a much better way. It’s called generics. Generics are a core feature of TypeScript that lets you write functions, classes, and interfaces that are flexible and reusable, all without sacrificing type safety. This guide explains what generics are, why they are so useful, and how you can start using them with practical examples. Before diving int…  ( 8 min )

You heard it right. AI coding assistants are writing code in every language, spinning up apps in every framework, and shipping stuff faster than most humans can even blink. People are freaking out, and the panic is mostly hitting software developers. “AI is gonna replace devs,” they say. But hold up. Why are we only sweating for web developers or software engineers? I see tons of new devs jumping into AI or ML thinking that’s the “safe” route. But here’s the kicker: AI can already write code to train models from scratch. It can generate full ML pipelines, build agents, and basically do everything except drink coffee. If you think switching stacks is gonna save you, you’re missing the bigger picture. The real deal is this: AI is gonna touch every freaking field, not just coding. Medic…  ( 7 min )

If you’ve ever used Apache ECharts with React, you know it’s a beast. You throw data at it, and it happily plots gorgeous charts. But one day, I threw too much data at it. Like, “boss wants all plants, all vendors, all months” kind of data. Instead of scrolling nicely, my chart shrunk itself to oblivion. Labels? Gone. Bars? Toothpick-sized. Me? Crying in console.log. By default, ECharts tries to fit all your data into the chart’s visible width. That means if you have 200+ bars, instead of scroll, you get… something that looks like a barcode scanner output. 🛒🔍 Instead of fighting with ECharts configs, I thought: “What if I just resize the chart width dynamically and let the parent div scroll?” That’s exactly what I did. And it works beautifully. 🎉 Here’s my actual React component (with F…  ( 7 min )

To be honest, most of the interviews I've had so far have been quite pleasant. The challenges I faced were primarily due to gaps in my knowledge, and my interviewers were generally very kind. However, one experience stands out vividly in my memory: about two years ago, I attended a tech job fair. At such events, the selection of candidates often boils down to a simple question: "Oh, so you're a programmer?" That's how I found myself in an interview with a company, despite clearly stating that a) I was a student and b) I had no idea what the job entailed. I can only imagine how frustrated their CTO must have been with the HR department for their lackluster selection process. During the interview, I recall him saying things like, "Oh, so you want to be a developer? You know that it's a job w…  ( 7 min )

1. Five Core Restrictions Libraries are powerful because of strict rules: Stateless: no state variables allowed. No inheritance: cannot inherit or be inherited. Indestructible: no selfdestruct. No payable/fallback: can’t hold ETH. No abstract functions: all must be fully implemented. These restrictions ensure predictability, safety, and trustworthiness. Normal call: Math.max(numbers) With using for: using Math for int[]; Compiler automatically passes the variable (numbers) as the first argument. Convention: call this parameter self (like this in OOP). This makes Solidity code feel more object-oriented. Solidity libraries are much more than a toolbox: Strict safety rules keep them pure and reliable. using for adds elegance and OOP-like syntax. Off-chain calls may be free, but on-chain execution still costs Gas. Deployable as shared infrastructure → true on-chain microservices. They’re not just helpers — they’re a core design pattern for secure, efficient, and modular smart contracts.  ( 6 min )

Kubernetes has become the de facto operating system for the cloud, empowering organizations to scale and orchestrate their workloads with unprecedented ease. But with this power comes a new set of challenges. As you break down monoliths into microservices and deploy hundreds or thousands of pods, each workload can become a potential black box. The very agility that makes Kubernetes so valuable also makes observability a monumental task. Prometheus and OpenTelemetry (OTel) emerged as the go-to tools for making these workloads observable, yet not every system plays by the same rules. A growing example is Model Context Protocol (MCP) servers, which often don't expose metrics at all, creating blind spots in even the most sophisticated monitoring stacks.

Why I Use Hurl for HTTP API Testing As a developer who often tests and experiments with APIs, I’m always on the lookout for simple yet powerful tools. Recently, I started using Hurl, and it’s quickly become one of my favorites for running and testing HTTP requests. Hurl lets me write HTTP requests in plain text files, exactly how I would type them in a terminal or Postman, but with the added ability to automate sequences and handle variables. This means I can chain requests, grab OAuth tokens from one response, and use them in the next request — all without writing complicated scripts in another language. It’s a command-line tool, which fits perfectly into my workflow and CI/CD pipelines. I appreciate that it’s lightweight, fast, and supports modern features like HTTP/2 and retries. The syntax is straightforward, so there’s almost no learning curve. Here’s a simple GET request I’ve used to fetch user data: GET https://api.example.com/users Accept: application/json HTTP/1.1 200 [Asserts] jsonpath "$.length()" > 0 And here’s how I retrieve an OAuth token and use it in another request: POST https://auth.example.com/oauth/token Content-Type: application/x-www-form-urlencoded grant_type=client_credentials&client_id=YOUR_ID&client_secret=YOUR_SECRET HTTP/1.1 200 jsonpath "$.access_token" != null [Capture] token = jsonpath("$.access_token") GET https://api.example.com/data Authorization: Bearer {{token}} HTTP/1.1 200 If you want to try it out, installing Hurl is easy with Homebrew: brew install hurl For more details and documentation, check out the official site: https://hurl.dev/ Hurl has simplified my API testing and automation work dramatically. If you want a no-fuss, scriptable way to run HTTP requests and manage OAuth tokens, give it a try — it might just save you a lot of time.  ( 6 min )

🔐 Fine-Grained Role Control for MCP Tools with APIM In an earlier article, we looked at how to enforce role-based access control (RBAC) for individual Logic App workflows by combining Azure API Management (APIM) with Easy Auth. 👉 The same principle now applies when you expose your Logic Apps MCP server through APIM. Instead of guarding workflows directly, we can protect MCP tools — making sure only users with the right role can invoke the right tool. MCP (Model Context Protocol) servers expose tools as callable operations. For example, an MCP server might surface tools like: wf_arithmetic_add wf_arithmetic_sub wf_arithmetic_div Without access control, any authenticated user could call any tool. But in many scenarios, you need fine-grained authorization: Finance users can only run …  ( 8 min )

Many people including me have been confused with the concept of understanding what is a pointer. Lets learn it the simple way Before learning the pointers lets do a conceptual/story type understanding of this. Scenario 1: Pass by Value (The Inefficient Way) void check_health(struct PlayerProfile player) every time you call it, the computer has to copy the entire structure. It's like photocopying a 200-page book every time you want to show someone a single sentence. This wastes memory and, more importantly, takes time. Scenario 2: Pass by Pointer (The Efficient Way) void check_health(struct PlayerProfile* player) you are not passing the book; you are just passing a small sticky note with the book's location in the library (its memory address). A memory address is tiny (usually 4 or 8 byte…  ( 7 min )

Design patterns are a classic way to solve recurring software design problems. Adapter pattern, but written in Clprolf — a language that makes object-oriented roles and contracts explicit. Even if you don’t know Clprolf yet, don’t worry: the use case is familiar, the solution is the same pattern you already know, and you’ll see how Clprolf makes both sides clearer. Imagine you have an existing class that implements an old interface, but your application now expects the modern version of that interface. You cannot change the old class (it’s legacy code, or external). You need a way to reuse it, but expose it through the newer contract. That’s where the Adapter comes in. In Clprolf, the rule is simple: A concrete agent can contract only one version_inh. So you cannot make the same class both…  ( 7 min )

Consistency Wins Over Talent: Jade Eddy proves that raw talent is only the starting point. Every breakthrough Jade Eddy has achieved comes from hours of dedicated practice, repetition, and refinement. For developers, this is the equivalent of committing code daily, refining projects, and staying consistent even when the results don’t come immediately. Jade Eddy reminds us that greatness comes from showing up, again and again. Creativity Thrives on Boundaries: While some people see boundaries as limitations, Jade Eddy sees them as opportunities for innovation. By respecting the traditions of bluegrass while pushing forward with new ideas, Jade Eddy has created a voice that is both authentic and fresh. Developers face the same challenge: working within frameworks, libraries, or legacy system…  ( 7 min )

"What should I test? What E2E test should I write?" - These were the questions that I heard from a teammate who was working on a task after a week. It reminded me of a bigger question: until when, or at what role, should you tell developers that they need to “brush their teeth”? Because there’s a difference between asking someone to do the basics and asking them to do the basics with quality. These are the hygiene factors — the equivalent of brushing your teeth: Write tests: unit, integration, maybe even some E2E depending on the context. At the very least, there’s a baseline every project should meet. Monitor and observe your deploys: it’s 2025 — observability shouldn’t be optional. At a minimum, you need visibility into your system’s behavior after a change. Deploy beyond your machin…  ( 7 min )

When AI coding agents first started buzzing around, I was skeptical. I thought, "Cool, another bot to generate ‘Hello World’ in 50 languages." But once I started using one, my perspective completely changed. I'd compare the experience to moving from endlessly Googling "why am I getting this error" to having a pair-programming partner in your editor, point at the bug, and say, "See that bug on line 42? This is how to fix it." I began exploring more AI coding agents and rethinking my development workflow when I came across Continue.dev, an open-source AI agent. I wondered how it stacked up against the popular ChatGPT. In this article, I will discuss what distinguishes these two tools. Feature/Aspect ChatGPT Continue Where it lives Browser (web-based) Inside your IDE (VS Code, JetBra…  ( 9 min )

Clean Architecture helps keep large applications maintainable by enforcing clear boundaries between UI, business rules, and infrastructure. This post walks through a pragmatic setup for a .NET API paired with Blazor Server using a classic three-layer dependency flow, a scalable folder structure, and a concrete use case wired end-to-end. It’s designed so features are testable, infrastructure is replaceable, and the UI stays clean. Why this matters Maintainability: Boundaries prevent “logic leakage” from UI to data access. Testability: Use cases are pure and easy to unit test. Flexibility: Infrastructure (DBs, HTTP clients) can be swapped without touching business logic. Velocity: Teams can work in parallel on Presentation, Application, and Infrastructure without stepping on each other. Cle…  ( 8 min )

Building a robust and cost-effective cloud architecture requires balancing security, scalability, and efficiency. In a recent project, we designed a single-ingress architecture using AWS API Gateway as the public entry point and an internal Application Load Balancer (ALB) to handle API requests and web traffic for a multi-tenant SaaS application. This setup uses a custom JWT authentication solution, integrates Web Application Firewall (WAF) protections on API Gateway, and optimizes costs for a lean deployment. In this article, I’ll share the high-level solutions architecture, configuration details, security considerations, cost-saving strategies, pros/cons, alternative architectures, why it’s suited for MVPs/small SaaS, and paths to enterprise scaling—for developers and architects explorin…  ( 11 min )

Artificial intelligence is fueling demand for high-performance compute across industries—from generative media to autonomous systems. Traditional solutions rely on large, centralized data centers. In contrast, Decentralized Physical Infrastructure Networks (DePINs) allow everyday users to contribute real-world resources like storage, bandwidth, and compute. Neurolov extends this model by introducing a browser-based GPU compute network, positioning itself within the DePIN landscape as a platform focused on accessible, distributed AI infrastructure. DePIN projects decentralize critical infrastructure by rewarding participants who contribute physical resources: Helium → bandwidth sharing Filecoin → decentralized storage Render → GPU rendering Neurolov adds GPU compute to this list,…  ( 7 min )

A love letter to every designer drowning in courses while their dreams collect dust Last Tuesday, my friend Sarah called me crying. Not the dramatic, something-terrible-happened kind of crying. The quiet, exhausted kind that comes from spending nine months preparing for a career that keeps moving further away the harder you chase it. "I just finished another $300 course," she said. "The instructor mentioned three new tools I've never heard of. I feel like I'm running backward." Sarah has 47 certificates. A Notion database with 200+ bookmarked "must-learn" resources. She can tell you the difference between atomic design and material design in her sleep. She's memorized every UX law from Fitts to Miller. She's also never designed anything that a real human being has actually used. And honest…  ( 11 min )
